ZR/ je I)e~criptïon Aryl halophosphoramidites, aryl phosphonamidites, proces-ses for their preparation and their use forthestabiliza-tion of plastics The present invention relates to new aryl halophosphor-amidites, monoaryl phosphonamidites and bis~aryl] diphos-phonamidites, processes for their preparation and their use for the stabilization of plastics.
It is known that synthetic polymers have to be protected by stabilizers or stabilizer systems against undesired oxidative, ~hermal and photochemical damage during preparation, processing and use. Such stabilizers are, for example, composed of a phenolic antioxidant and one or more costabilizers, some of which are also able to reinforce the action of the phenolic ~omponents syner-gistically.
The most used stabilizers include, for ex~mple, phosphor-ous acid and phosphonous acid derivatives, the latter, above all, being distinguished by a ~ery good stability to hydrolysis.
The synthesis of phosphonamidites by stepwise reaction of dihalophonites with alcohols or phenols and amines in the presence of acid acceptors has been described by various authors [Houben-Weyl, Methoden der organischen Chemie (Methods of Organio Chemistry), phosphorus compounds El p. 300 (1982)~. The yields obtained in these processes were only about 60-75%.
In an analogous manner, suitable monophosphonamidites for use as stabilizers for polymers are prepared by reaction of alkyl or aryl dihalophosphonites, for example chloro-phosphonites, with phenols and amines in the presence of excess base, which is used to neutralize the hydrochloric

acid formed, according to EP Offenlegunqsschrift 42,359.
Data relating to the purity of the products or ~he yields achieved are not given there.
However, the process of EP Offenlegungsschrift 42,359 can only be carried ou~ to a limited extent because of the difficult preparation of the dihalophosphanes needed as precursors which is, of cour~e/ disadvantageous if industrial production is considered. Thus, for ex2~mple, of the aromatic derivatives, only phenyldichlorophosphane is an industrially available product through which solely derivatives of benzenephosphonous acid are available.
This is confirmed in that in EP Offenlegungsschrift 42,359, except for one, all (no less than 17) ex2~mples contain the unsubstituted phenyl radical.
In addition to the achievement of higher yields, it is desirable for fulfilling the high requirements which are placed on the stability, activity, low volatility and the migration behavior of such stabilizers in practice to have available directly derivatives of aryl phosphonous acids substituted in the phenyl radical. However, their availability by known methods founders on the fact that appropriately substituted precursors are needed for this purpose, which are hitherto unknown or cannot be prepared economically~
It is therefore also an ob~ect of the invention to prepare novel stabilizers for plastics having improved properties, in particular with the aid of processes which do not have such disadvantages.
The present invention relates to aryl phosphon2~midites of the formula ~I) ¦ f ~ ~3 (I) \
~ 5 tl in which:
Rl, as a uniYalent radical, i5 a phenyl radical which carries 1 to 3 substituent~, or a benzyl, ~-methylbenzyl or ~ dLmethylbenzyl radical which in each case can car~y 1 to 3 substituents on the nucleus, or a naphthyl radical which can carry 1 to 5 ~ubstituent~, where at least one of these substituents i~ an alkoxy radical or alkylthio radical in each case havins 1 to 8, preferably 1 to 6, carbon atoms, or an aryl or aryloxy radical in each case having 6 to 10, preferably 6 to 8, carbon atoms or halogen having an atomic number of 9 to 35 and the other substituents - also exclusively in the naphthyl radical - are a non-aromatic hydrocarbon radical having 1 to 8 carbon a~om~, and R~, as a divalent radical, is a phenylene radical which is unsubstituted or substituted by up to 2 non-aroma~ic hydrocarbon radical~ having 1 to 8 carbon atom~, or a naphthylene or biphenylene radical which is unsub~tituted ox can carry 1 to 4 non-aromatic hydrocarbon radicals each having 1 to 8 carbon atoms a~
s~bstituents, R2 i~ a non-~romatic hydrocarbon radical having 1 to 18 carbon atoms, an a~yl or an optionally substituted arylmethyl radical, where the aryl radical in each case contain~ 6 to 10 carbon atom~, R3 i~ hydrogen, an alkoxy or alkylthio radical in each ca e having 1 to 18 carbon atoms or a group mentioned under R2, R' and R5 independently of one a~other in each case are Cl-C22-alkyl, C2-C2l-oxaalkyl or -thiaalkyl, C3-C~8-alkenyl or -alkynyl, C3-C24-alkoxycarbonylalkyl, C5~Cl2~cycloalkyl, C6-Cl4-aryl, C7-Cl5-arylalkyl or an optionally substituted C5-Cl7-piperidin-4-yl group, or R4 and R5, together with the ni~rogen atom, are also a ring system containing 5 to 7 ring atoms which may additional-ly further contain a heteroatom (O, N, S~ bonded via at least one carbon atom and n = 1 or 2.
If n = 1, the compounds are phosphonamidites and if n =
2 the compounds are bis-diphosphonamidites.
A preferred group of compounds are those in which Rl, as a divalent radical, forms a biphenylene radical, R2 and R3 in each case form a branched butyl radical and R4 and R5 in each case form a butyl radical orl together with the nitrogen atom, form ~he morpholide radical.
Other preferred compounds are those in which R1 is the trimethylphenyl radical r R2 and R3 are the methyl radical or a branched butyl radical and R4 and Rs, ~ogether with the nitrogen, are either the piperidide or morpholide radical or in which Rl is ~he tert.-butyl-l-phenyl radi-cal, R2 is the tert.-butyl radical, R~ is the methoxy radical or t~rt.-butyl radical and R4 and R5, together with the nitrogen atom, are the morpholide radical.
Furthermore, those compounds in which R1 is unsubstituted or substituted naphthyl are particularly preferred.
In R1, the substituents can in each case be identical or different. The alXyl in the substitu0nts of the aromatic radicals Rl is, for e~ample, one of the various hexyl or octyl radicals, but preferably ha~ 1 to 4 carbon atoms and is, for example, methyl, ethyl or one of the various propyl or butyl radicals, which are optionally bonded to the nucleus via O or S. Cs-C~-cycloalkyl may be mentioned as a non-aromatic hydrocarbon radical, like the radicals mentioned further below under R2. In particul~r, for example, the anisyl radicals or naphthyl radicals may be mentioned, which, for example, further carry up to 2 substituents containing altogether up to 4 alkyl carbon atoms, and also the various biphenyl radicals.
For R1 as a divalent radical, the various phenylene radi-cals may, for example, be mentioned which are unsub-stituted or carry 1 to 2 C1-C8-alkyl groups, in particular Cl-C3-alkyl groups, or the various naphthylene radicals and biphenylene radicals which are unsubstituted or substituted by 1 to 4, preferably 1 to 3, Cl-C~-alkyl groups, in particular C1-C3-alkyl groups.
Naturally, the substituents in Rl can only be combined in such a way that no steric hindrance occurs. If R1 contains
acid formed, according to EP Offenlegunqsschrift 42,359.

Naturally, the substituents in Rl can only be combined in such a way that no steric hindrance occurs. If R1 contains
3 substituents, no more than 5 carbon atoms should be present in the two o-positions. In substituted naphthyl radicals which c~ntain more than two s~bstituents, these are advantageously distributed on both rings.
Suitable R2 and R3 radicals are, for example, non-aromatic hydrocarbon radicals having 1 to 18 carbon atoms, such as alkyl or cycloalkyl, and furthermore aromatic radicals which have 6-18 carbon atoms including aliphatic groups, where no more than 10 carbon atoms are part of an aroma-tic ring system. Preferably, the radicals R2 and R3 contain 4 to 12 and, in particular, 6 to lO carbon atoms.
In particular, the following may be m~ntioned as non-aromatic hydrocarbon radicals: alkyl, such as methyl, ethyl, the various propyl, butyl, pentyl, hexyl, octyl, decyl, dodecyl, hexadecyl and octadecyl radicals, and cycloalkyl havin~ 5 to lO carbon atoms such as cyclopen-~yl, cyclohexyl, cycloheptyl and cyclohexylmethyl (i.e.
both the hydrogenated ben~yl radical and the methyl-cyclohexyl radical); C5 C10-aryl and arylmethyl may further be mentioned, where the term aryl in each case includes alkylaryl, carries at most three of the sub-s~ituents mentioned under R2 and, including this, has at 6 ;~5~
most 14 carbon atoms.
If one of the radicals R2 or R3 is an alkyl r~dical, tertiary alkyl groups containing 4-10 carbon atoms, such as tert.-butyl, 2-methyl-2-butyl, 2-methyl-2-pentyl and 2-ethyl-2-butyl are particularly preferred. Other pre-ferred compounds are those in which R2 or R3 is phenyl, benzyl, ~-methylbenzyl and ~,~-dimethylbenzyl.
R4 and R5 are, for example, the radicals indicated for R2.
If they are alkyl, Cl-Cl2-alkyl groups are preferred.
R4 and R5, as C2-C21-oxa- or thiaalkyl, are, for example, methoxymethyl, methylthiamethyl, ethoxymethyl, methyl-thiaethyl or ethoxyethyl. Alkoxypropyl and slkylthia-propyl groups are preferred, such as methoxypropyl, ethylthiapropyl, butoxypropyl, octylthiapropyl, dodecyl-lS oxypropyl, octadecylthiapropyl or octadecyloxypropyl.
R4 and R5 are, as C3-C18-alkenyl, for example allyl, methallyl, n-hexen-3-yI, n-octen-4-yl, n-undecen-10-yl or n-octadecen-17-yl. Allyl and methallyl are preferred.
R4 and R5, as C3-C1~-alkynyl are, for example, propargyl, n-butyn-l-yl, n-butyn-2-yl or n-hexyn-l-yl. Alkynyl groups having 3-6 carbon atoms are preferred, in par-ticular propargyl.
If R4 and R5, together with the nitrogen atom to which they are bonded, form a pyrrolidine, oxazolidine, piperi-dine, morpholine, hexamethyleneimine or piperazine ring,these heterocycles can be substituted by 1 to 5, ad-vantageously at most 2, methyl or ethyl groups. Ring systems of this type are preferably unsubstituted.
If R4 and R5 are piperidin-4-yl groups, they may be unsubstituted piperidin-4-yl, or the piperidine may be substituted by up to 5 alkyl groups. The 2,2,6,6-tetra-methylpiperidin-4-yl radical is particularly preferred.
The invention also relates to a process for the prepara-tion of phosphonamidites of the formula ~I) in which Rl, as a univalent radical, in addition to the abovementioned meaning can also be phenyl and a phenyl substituted by 1 to 3 non-aromatic hydrocarbon radicals having 1 to 8 carbon atoms, and a non-aromatic hydrocarbon radical having 1 to 18 carbon a~oms, preferably Cl-Cl8-alkyl, and R2, R3, R4 and R5 have the abovemention d meaning, which comprises initially reacting in a first step a halide Rl(-X)n in which Rl has the abovementioned meaning, n = 1 or 2 and X is a halogen having an atomic weight of at least 35, preferably chlorine or bromine, under Grignard conditions, i.e. advantageously with intimate mixing, with finely particulate magnesium to give the corresponding Grignard compounds R1(MgX)n and reacting these in a second step with aryl halophosphoramidites of the formula (II) ~2 O ~ ~3 X--N
in which R2 R3, R4 and Rs have the abovementioned meaning and X is chlori.ne or bromine, to give the phosphonamid-ites (I). The process according to the invention is thus also utilizable for the reaction of those compounds of the formula R1(MgX)n in which Rl, for example, is the tolyl, dimethylphenyl, trimethylphenyl or tert.-butyl-phenyl radical.
With respect to economic accessibility~ those of thecompounds (II) where ~ = chlorine are particularly preferred.
The first step of the process according to the invention which can be carried out in any customary manner, i5 preferably carried out in an aprotic organic solvent, such as an ether, for example diethyl, dipropyl or diisopropyl ether, ethylene glycol dimethyl ether or ethylene glycol diethyl ether, diethylene glycol dLmethyl ether or diethylene glycol diethyl ether, methyl tert.~
butyl ether, dioxane or tetrahydrofuran.
As the Grignard compounds are sensitive to hydrolysis and oxidation, it is advantageous to work under a protective gas atmosphere, however, such a process is not compulsory for the success of the reaction. Nitrogen and argon are particularly suitable as protective gases.
The reaction temperature during the conversion into a Grignard compound is in general between 20 and 125C, preferably between 30 and 70C. The effect of ultrasound during the conversion into a Grignard compound is some-times advantageous.
In order to prepare the final product (I), the solution ox suspension of the Grignard reagent in the second step is metered into the halophosphoramidite (II) which is advantageously diluted with an inert, aprotic solvent~
for example an aliphatic hydrocarkon fraction, hexane, cyclohexane, toluene, xylene or one of the abovementioned ethers, advantageously at a temperature below 0C. The reaction temperature in this step is in general between 30C and +50C, but preferably between -20C and +20C.
As a rule, the reaction proceeds exothermically; accord-ingly it may be expedient to control the course of the reaction by cooling. The most favorable results are achieved if the reaction components are employed accord-ing to the reacti.on stoichiometry. However, it is also possible to employ one reaction component in excess;
however, in general there are no particular advantages associated with this. The mixture is expediently stirred until the reaction i~ complete, and precipitated mag-nesium halide is subssquently separated off. The solvents ;~?~
g can be removed from the filtrate in a customary manner, advantageously by distillation, in particular under reduced pressure.
The synthesis of phosphonamidites with the aid of organo-metallic compounds, for example by reaction of halo-phosphoramidites with Grignard reagents, was hitherto unknown. Ob~iously, owing to the known easy replaceabil-ity of amino groups and also ester groups bonded to the phosphorus by nucleophiles [Houben-Weyl, Methoden der organischen Chemie (Methods of Organic Chemistry), volume 12/1, 44, (1963) and E 1,302 (1982)], a prejudice existed in this respect in that in th~ reaction of halophosphor-amidites with Grignard reagents, to a high extent side reactions reducing the yield with its progress and a still lower yield of desired product ca~sed as a result may have to be taken into account.
It is therefore particularly surprising that, starting from easily accessible halophosphoramidites, any sub-stituted phosphonamidites can be obtained in such a high 2Q yield and purity according to the proces~ of the present invention.
The products (I) can be separated from the crude products ~y any desired processess, but preferably by crystalliza-tion.
The halophosphoramidites (II) required as starting compounds, which are new except for that compound in which X is chlorine, R2 is methyl, R3 is hydrogen and R4 and R5 are in each case ethyl [Izv. Akad. Nauk. SSSR, Ser.
Khim., (9), 2131~2133 (1968)], can be prepared in a simple manner by a process to which the invention also relates. However, this known compound has achieved no industrial Lmportance. It is particularly unsuitable as a starting material for stabilizers fox polymers.
The invention thus also relates to a process for the lo- 2~5~
preparstion of these compound~ (II), which comprises reactinq an aryl dihalopho~phite of the formula ~III) p _ 0 ~ 3 (III) with an amine of the formula XNR~R5 (IY) in the presence S of at least an equimolar amount of an acid-binding agent, where, in the formulae (III) and (IV), R2, R3, R~ and R5 have the meanings which are indicated for the process for the preparation of the compounds (I) and X is a halogen having an atomic weight of at least 35. The process thus also extends to the preparation of the compound of the formula (II) in which X is chlorine, R2 is methyl, R3 is hydrogen and R4 and R5 are in each case ethyl, which has hitherto been prepared in another manner.
This process can be carried out per se in any customary lS manner. It is preferably carried out in an inert aprotic solvent. Hydrocarbons such as pentane, hexane, heptane, benzene, toluene, xylene, chlorobenzene and ethers such as diethyl ether, dipropyl ether, diisopropyl ether, ethylene glycol dimethyl ether or ethylene glycol diethyl ether are particularly suitable for this purpose.
The compound~ of the formula (II) are expediently prepar-ed by adding an equimolar amount of the amine (IV) and an equimolar amount of a base suitable as an acid-binding agent to the solution of the dihalide (III) with vigorous mixing. In this case the reaction i~ in general carried out between -30 and +30-C, preferably between -20 and ~lO-C. The mixing is carried out, for exampIe, by stir-ring and, expediently, until the reaction i8 complete.
~he precipitated ammonium ~alt i~ then separated off. The solvents can be removed from the filtrate in a customary .. . .

Suitable bases, which are advantageously dil~l-ted with one of the abovementioned solven~s, are, above all, tertiary amines, such as trie~hylamine and pyridine. An excess of amine HNR4R5 can also act as an acid-binding agent.
The products (II) obtained in this procedure are usually obtained in a purity which is easily sufficient for reaction with the Grignard compounds. A further purifica-tion, for example by vacuum or thin-layer distillation, is therefore as a rule unnecessary.
The invention finally relates to the use of the compounds of the formula (I) alone or in combination with a pheno-lic antioxidant for the stabilization of plastics, such as polycarbonates, preferably polymerization plastics such as polyolefins, in particul~r polypropylene. The compounds of the formula (I) impart an Lmproved stability against degradation by light, oxygen and heat to the plastics in the molding compositions. However, the purity of the crude reaction product obtained (85-93% according to 31P-NMR) iS frequently sufficient for this use. Isola-tion in a pure form is then unnecessary.
The present invention thus also relates to a plastic molding composition, containing a thermoplastic or thermoset material and an aryl phosphonamidite of the formula (I) in the ratio of (90 to 99.99):(0.01 to 10).
The plastic molding composition according to the inven-tion contains a thermoplastic or thermoset organic polymer, for example one of the following:
1. Polymers of mono- and diolefins,forexample polyethyl-ene of high, medium or low density (which, if desired, can b~ crosslinked), pol~ypropylene, polyisobutylene, poly-1-butene, polymethyl-1-pentene~ polyisoprene or polybutadiene and polymers of cycloolefins, such as, for example, cyclopentene or norbornene.
2. Mixtures of the polymers mentioned under l), for example mixtures of polypropylene with polyethylene or with polyisobutyl~ne.
3. Copolymers of mono- and diolefins with one another or wi~hother vinyl monomers, such as, for example, ethylene-propylene copolymers, propylene-l-butene copolymers, propylene-isobutylene copolymers, ethylene-l-butene copolymers, propylene-butadiene copolymers, isobutylene-isoprene copolymers, ethylene-alkyl acryla~e copolymers, ethylene-alkyl methacrylate copolymers, ethylene-vinyl acetate copolymers or ethylene-acrylic acid copolymers and salts ~hereof tionomers) and terpolymers of ethylene with propylene and a diene, such as hexadiene, dicyclo-pentadien~ or ethylidenenorbornene.
Suitable R2 and R3 radicals are, for example, non-aromatic hydrocarbon radicals having 1 to 18 carbon atoms, such as alkyl or cycloalkyl, and furthermore aromatic radicals which have 6-18 carbon atoms including aliphatic groups, where no more than 10 carbon atoms are part of an aroma-tic ring system. Preferably, the radicals R2 and R3 contain 4 to 12 and, in particular, 6 to lO carbon atoms.

Other pre-ferred compounds are those in which R2 or R3 is phenyl, benzyl, ~-methylbenzyl and ~,~-dimethylbenzyl.
R4 and R5 are, for example, the radicals indicated for R2.
If they are alkyl, Cl-Cl2-alkyl groups are preferred.
R4 and R5, as C2-C21-oxa- or thiaalkyl, are, for example, methoxymethyl, methylthiamethyl, ethoxymethyl, methyl-thiaethyl or ethoxyethyl. Alkoxypropyl and slkylthia-propyl groups are preferred, such as methoxypropyl, ethylthiapropyl, butoxypropyl, octylthiapropyl, dodecyl-lS oxypropyl, octadecylthiapropyl or octadecyloxypropyl.
R4 and R5 are, as C3-C18-alkenyl, for example allyl, methallyl, n-hexen-3-yI, n-octen-4-yl, n-undecen-10-yl or n-octadecen-17-yl. Allyl and methallyl are preferred.

If R4 and R5, together with the nitrogen atom to which they are bonded, form a pyrrolidine, oxazolidine, piperi-dine, morpholine, hexamethyleneimine or piperazine ring,these heterocycles can be substituted by 1 to 5, ad-vantageously at most 2, methyl or ethyl groups. Ring systems of this type are preferably unsubstituted.
If R4 and R5 are piperidin-4-yl groups, they may be unsubstituted piperidin-4-yl, or the piperidine may be substituted by up to 5 alkyl groups. The 2,2,6,6-tetra-methylpiperidin-4-yl radical is particularly preferred.
The invention also relates to a process for the prepara-tion of phosphonamidites of the formula ~I) in which Rl, as a univalent radical, in addition to the abovementioned meaning can also be phenyl and a phenyl substituted by 1 to 3 non-aromatic hydrocarbon radicals having 1 to 8 carbon atoms, and a non-aromatic hydrocarbon radical having 1 to 18 carbon a~oms, preferably Cl-Cl8-alkyl, and R2, R3, R4 and R5 have the abovemention d meaning, which comprises initially reacting in a first step a halide Rl(-X)n in which Rl has the abovementioned meaning, n = 1 or 2 and X is a halogen having an atomic weight of at least 35, preferably chlorine or bromine, under Grignard conditions, i.e. advantageously with intimate mixing, with finely particulate magnesium to give the corresponding Grignard compounds R1(MgX)n and reacting these in a second step with aryl halophosphoramidites of the formula (II) ~2 O ~ ~3 X--N

The process according to the invention is thus also utilizable for the reaction of those compounds of the formula R1(MgX)n in which Rl, for example, is the tolyl, dimethylphenyl, trimethylphenyl or tert.-butyl-phenyl radical.
