1,274,837. Allyl esters. FARBENFABRIKEN BAYER A.G. 22 June, 1970 [2 July, 1969], No. 30130/70. Heading C2C. Allyl esters are prepared by reacting allyl acetate with a carboxylic acid methyl or ethyl ester in the presence of an alkoxide of a metal of Periodic Groups Ia, IIa, IIIa (Mendeleev) or a complex salt thereof. An excess of the allyl acetate is used and saturated and unsaturated aliphatic and cycloaliphatic, substituted aliphatic, cycloaliphatic, araliphatic mono- and polycarboxylic acids and aromatic mono- and polycarboxylic acids and carbonic acid are listed. The catalysts may be lithium, sodium, potassium, magnesium, calcium methylates or mixed methylates and others. Examples describe the reaction of allyl acetate with methyl propionate, methyl stearate, hexahydrobenzoic acid methyl ester, adipic acid dimethyl ester, chloracetic acid ethyl ester, dichloroacetic acid methyl ester, ethoxyacetic acid methyl ester, diglycolic acid dimethyl ester, phenyl acetic acid methyl ester, methyl acrylate, methyl methacrylate, ethyl cinnamate, methyl sorbate, maleic acid dimethyl ester, methyl benzoate, dimethyl phthalate, dimethyl terephthalate, and carbonic acid diethyl ester.
