Abstract: 2-alkyl-4,4-diacyloxybut-2-enals of the formula I where R1 is alkyl and R2 and R3 are each hydrogen or an aliphatic, cycloaliphatic or aromatic radical, are prepared by a process wherein a 2-alkyl-2,4-diacyloxybut-3-enal of the formula II is treated with an aliphatic carboxylic acid.

Abstract: (I), prepn. by reaching butenediol esters, (II), with at least equiv. quantities of HCN at 60-160 degrees C., takes place in aq. solns. of CuBr contg. alkali bromide, under pressures >=2 (pref. 2-20) bar. Mol. ratio CuBr to (II) is (0.3-0.6) : 1. The alkali bromide is esp. NaBr. The aq. solns. pref. also contain NH4Br and up to 10 wt.% HBr. (I) can be hydrogenated to hexamethylene diamine, used in polyamide prodn. On replacing previously used CuCl + alkali halide by CuBr + alkali bromide, yields of (I) can be increased, e.g. from 30% to >80%. Process can be effected economically on a large scale. Aq. solns. are handled more easily than fused salts. (I) is easily separated.

Abstract: A process for the preparation of a diacyloxyhexadiene of the formula I where X is R9-CO- and R1 to R9 are hydrogen or alkyl of 1 to 3 carbon atoms, by reacting a hexatriene of the formula II with oxygen and a carboxylic acid of the formula R9COOH in the presence of a catalyst which contains palladium, platinum or a salt of these metals.
