Abstract

Halides of unsaturated aliphatic carboxylic acids are prepared by contacting a compound containing the grouping <FORM:0987274/C2/1> wherein X is a halogen atom and the free valencies indicated are attached to hydrogen atoms or alkyl groups, with carbon monoxide in the presence of palladium or a complex or a salt thereof at a temperature of at most 250 DEG C. and at a pressure of at most 3000 atmospheres. The acid halides may be reacted subsequently with water, an alcohol, ammonia or an amine to give, respectively, the corresponding acid, ester or unsubstituted or substituted amide. In a modification of the process the acid, ester or amide is produced directly by conducting the carbonylation reaction as above in the presence of water, an alcohol, ammonia or an amine. Specified catalysts are metallic palladium, palladous chloride, p -allyl palladium chloride, p -methallyl palladium chloride and p -crotyl palladium chloride. Examples are given. The following conversions of starting materials also occur in the examples:-(6) 1-chlorobut-2-ene to 3 - chlorobut - 1 - ene; (7) 3 - chlorobut - 1 - ene to 1-chlorobut-2-ene; (8) methallyl chloride to tertiary-butyl chloride.
