619523 COMMONWEALTH OF AUSTRALIA PATENTS ACT 1952 COMPLETE SPECIFICATION NAME ADDRESS OF APPLICANT: Atochem La Defense 4 8 Cours Michelet Puteaux 92800 France NAME(S) OF INVENTOR(S): Michel DEVIC Jacques KERVENNAL ADDRESS FOR SERVICE: C t DAVIES COLLISON Patent Attorneys 1 Little Collins Street, Melbourne, 3000.
COMPLETE SPECIFICATION FOR THE INVENTION ENTITLED: Process for the diacylation of compounds containing two aromatic rings The following statement is a full description of this invention, including the best method of performing it known to me/us:ir' A ii i 2 The present invention relates to a process for the diacylation of compounds having two aromatic rings in their molecule, of general formula: wherein X denotes an oxygen or sulphur atom, or a or -CH 2 group,
R

R
2 R3, R 4 are identical or different and represent a hydrogen atom or an alkyl group having 1 to 4 carbon atoms.
Diacylation is to be understood to mean the conversion of a compound of general formula to a compound of general formula:
C-R

C
CI-
I R R being as defined above.
Examples of acylating agents thus defined are given, for example, in EP-A-069597.
The compounds of formula (II) are used in industry as intermediates, for example to produce polyester-type polymers. This is particularly so in the case of those in which R is in positions 4 and such as 4,4'-diacetyldiphenyl ether: CH 0 0-0 C-CH 0 0 The acylation of diphenyl ether to form, for example, 4 -phenoxyacetone: S4 CH3-C 0
O
as described for example in the abovementioned European Patent Application, is known.
This same Application teaches that acylation in the presence of hydrofluoric acid HF practically excludes Et diacylation, which however does occur in the presence of aluminium chloride A1C1.
tin" The drawbacks attending the latter's use are known to limit its industrial interest to a large extent.
The present invention enables such a choice to be avoided and can lead to highly pure products of formula in a very high chemical yield, or yield in terms of the diacylation of the compound of general formula SThe present invention provides a process for the diacylation of compounds of general formula to compounds of general formula by bringing a compound of general formula into contact with an acylating agent of general formula (III) in anhydrous medium, characterized in that this bringing into contact is effected at a temperature 0 0 between -40 C and 0°C in the presence of hydrofluoric acid HF, boron fluoride BF 3 and at least 2 moles of acylating agent of general formula (III) per mole of compound of general formula The aim of the invention, diacylation of a compound
Y
I I 5 of general formula is most generally achieved when 1 to moles of HF and 5 to 20 moles of BF 3 are present per mole of the said compound.
The BF3/HF molar ratio which is often most preferable is from 10/1 to 0.5/1.
The molar ratio of acylating agent to compound of formula is usually limited to a value not exceeding 5/1.
The most commonly used acylating agents are acid Schlorides and acid anhydrides, in particular acetyl chloride 10 and acetic anhydride.
The presence of a.solvent in the acylation medium may be useful, in particular for facilitating solubilization of the compound of general formula and contact between the components of this medium.
J 15 The solvent may be one of those that are known to be suitable for Friedel-Crafts reactions such as dichloromethane, nitromethane or carbon disulphide.
The process of the invention can be carried out in S any equipment that will resist pressure, and HF, BF 3 under the conditions defined above, such as a stainless steel autoclave.
The operation according to the invention is usually fast. Its duration is, for example, of the order of 1 hour, and even less.
The following Examples further illustrate the invention.
6 In all these Examples, the compound of general formula the acylating agent, HF, BF 3 and, where present, the methylene chloride used as solvent, are brought into contact in a stirred stainless steel autoclave for 1 hour, purity is understood to mean the purity, expressed as by weight, of the compound of general formula (II) obtained by addition of water and sodium hydroxide once autoclaving is over, followed by filtration and washing with 1, 0 water, and drying under vacuum at 80 C, S. chemical yield is understood to mean the number of moles, expressed as of compound of general formula (I) converted to compound of general formula (II), the analytical methods are liquid phase chromatography and nuclear magnetic resonance (NMR).
Example 1: Diphenyl ether: is brought into contact at -40 0 C with (per mole of diphenyl ether) 2.2 moles of acetic anhydride, 10 moles of HF and moles of BF 3 The purity of the 4,4'-diacetyldiphenyl ether obtained and the chemical yield are above 98 i 7 Example 2: Diphenyl sulphide:
SQ
is brought into contact at 0 C with (per mole of diphenyl sulphide) 3 moles of acetyl chloride, 10 moles of HF, moles of BF 3 and 200 g of methylene chloride.
0o0 The purity of the resulting 4,4'-diacetyldiphenyl o.O sulphide obtained is equal to 96 and the chemical yield is So"Q' equal to 90 00 10 Example 3: p-Diphenylbenzene: coeo .e is brought into contact at 0°C with (per mole of p-diphenyl- 92 20 Example 4: CH 2 benzene) 3 moles of acetyl chloride, 20 moles of HF, moles of BF 3 and 400 g of methylene chloride.
The purity of the 4,4'-diacetyldiphenylbenzene obtained is above 98 and the chemical yield is equal to 92 Example 4: Diphenylmethane: OCH2 o 0 8 is brought into contact at -20 0 C with (per mole of diphenylmethane) 2.2 moles of acetic anhydride, 2.5 moles of HF, moles of BF 3 and 200 g of methylene chloride.
The purity of the 4,4'-diacetyldiphenylmethane obtained is equal to 90% and the chemical yield is equal to Example m-Benzyltoluene: #tti C H 3
CH

Q
*e is brought into contact at 0° C with (per mole of m-benzyltoluene) 3 moles of acetyl chloride, 2.5 moles of HF and moles of BF 3 J The chemical yield is 80 and the product obtained has a purity of 90 with respect to diacetyl compounds, in particular those acylated at positions 4 and 4'.
