Definitions
- the invention relates to a process for the production of organic compounds by producing aryllithium compounds and their reaction with suitable electrophiles, a lithium compound being initially generated by reaction of halogen compounds with lithium metal, which is then reacted to deprotonate aromatic compounds to form the desired lithium aromatics, wherein this is finally reacted with an appropriate electrophile if necessary (equation I),
- Step 1 creating the base lithium
- Step 2 deprotonation of the substrate
- Li-organyls can also be produced by reacting bromoaromatics with lithium metal (3)
- the deprotonation of organic is also very important
- n-, s- and tert-butyllithium produce either butanes (deprotonations), butyl halides (halogen-metal exchange, 1 equivalent of BuLi) or butene and butane (halogen-metal exchange), which are gaseous at room temperature and escape the reaction mixtures during the required hydrolytic work-ups.
- butyl halides halogen-metal exchange, 1 equivalent of BuLi
- butene and butane halogen-metal exchange
- the present invention solves all of these problems and relates to a process for the preparation of aryllithium compounds of the formulas (IV) and (VI) and, if appropriate, further reaction of these compounds with suitable electrophiles, a lithium compound initially being obtained by reacting halogen compounds (I) with lithium metal (II) is generated, and this is reacted with aromatic compounds of the formulas (III) and / or (V) with deprotonation and formation of the desired lithium aromatics (IV) and / or (VI) (equation I).
- Step 1 creating the base
- Step 2 deprotonation of the substrate
- R is methyl, primary, secondary or tertiary alkyl radicals having 2 to 12 carbon atoms, with a radical from the group ⁇ phenyl, substituted phenyl, aryl, heteroaryl, alkoxy, dialkylamino, alkylthio ⁇ substituted alkyl, substituted or unsubstituted cycloalkyl having 3 up to 8 carbon atoms,
- Xi ⁇ independently of one another represent carbon, the grouping X- R- can mean nitrogen, or two adjacent radicals XM RI-4 can jointly represent O (furans), S (thiophenes), NH or NR ', where R' is Ci - C 5 alkyl, S0 2 phenyl, SO 2 p-tolyl or benzoyl.
- Preferred compounds of the formula (III) which can be reacted by the process according to the invention are, for example, benzenes, pyridines, pyridazines, pyrimidines, pyrazines, furans, thiophenes, N-substituted pyrroles, benzofurans, indoles or naphthalenes, to name just a few.
- radicals R ⁇ and the radical Z stand for substituents from the group ⁇ hydrogen, methyl, primary, secondary or tertiary, cyclic or acyclic alkyl radicals having 2 to 12 carbon atoms, substituted cyclic or acyclic alkyl groups, alkoxy, dialkylamino, alkylamino, arylamino , Diarylamino, phenyl, substituted phenyl, alkylthio, diarylphosphino, dialkylphosphino, dialkyl- or diarylaminocarbonyl, monoalkyl- or monoarylaminocarbonyl, CO 2 " , hydroxyalkyl, alkoxyalkyl, fluorine or chlorine, CN or heteroaryl- ⁇ , each having two adjacent radicals R ⁇ _ 4 can correspond to an aromatic or aliphatic ring.
- the lithium organyls prepared in this way can be reacted with any electrophilic compounds by methods of the prior art.
- C, C linkages can be carried out by reaction with carbon electrophiles
- boronic acids can be prepared by reaction with boron compounds
- an efficient route to organosilanes is opened up by reaction with halogen or alkoxysilanes.
- reaction is carried out in a suitable organic solvent; ethereal solvents, for example tetrahydrofuran, dioxane, diethyl ether, di-n-butyl ether, diisopropyl ether or anisole are preferred, and THF is preferably used.
- ethereal solvents for example tetrahydrofuran, dioxane, diethyl ether, di-n-butyl ether, diisopropyl ether or anisole are preferred, and THF is preferably used.
- the preferred reaction temperatures are in the range from -100 to + 25 ° C, temperatures from -80 to -25 ° C are particularly preferred.
- Another advantage of the method according to the invention is that it is possible to work with organolithium compounds at very high concentrations. Concentrations of the aliphatic or aromatic intermediates of formula (II) of 5 to 30% by weight, in particular 12 to 25% by weight, are preferred.
- haloalkane and aromatic substrate are metered in simultaneously or as a mixture to lithium metal in the ether.
- the lithium aliphatic initially forms, which then immediately deprotonates the aromatics.
- the lithium can be used in the present process as a dispersion, powder, chips, sand, granules, pieces, bars or in another form, the size of the lithium particles not being quality-relevant, but rather only influencing the reaction times. Smaller particle sizes are therefore preferred, for example granules, powders or dispersions.
- the amount of lithium added is 1.95 to 2.5 mol, preferably 1.98 to 2.15 mol, per mole of halogen to be reacted.
- Aromatics which can be used for deprotonation are initially all compounds which are sufficiently acidic to be able to be deprotonated under the conditions according to the invention. All the aromatics which have "ortho-directing substituents" Z must first be mentioned here, that is to say in particular aromatics which carry alkoxy, F, Cl, substituted amino, CN, heteroaryl, aminoalkyl, hydroxyalkyl or similar radicals. The mode of action of such radicals is is based on the fact that these substituents enable the coordination of the lithium ion of the aliphatic base, as a result of which the counter ion R "can then very easily deprotonate in the ortho position.
- the lithium aromatics generated according to the invention can be reacted with electrophilic compounds by the methods familiar to the person skilled in the art, carbon, boron and silicon electrophiles in particular being of interest to the pharmaceutical and agrochemical industry with regard to the intermediate products required.
- the reaction with the electrophile can either take place after the production of the lithiated compound ((IV) and / or (VI) or, as already described above, in a one-pot process by simultaneous addition to the reaction mixture.
- the carbon electrophiles come in particular from one of the following categories (the products in brackets):
- Azomethine (ArCR 1 2 -NR ⁇ ) Nitroenolate (Oxime) Immonium salts (aromatic amines)
- Alkali and alkaline earth salts of carboxylic acids (ArCHO for formates, ArCOCH 3 for
- Aromatic nitriles (ArCOAr ')
