Abstract: 1,125,158. Carbonylation of unsaturated compounds. BADISCHE ANILIN- & SODAFABRIK A.G. 17 Dec., 1965 [19 Dec., 1964], No. 53574/65. Heading C2C. In a process for preparing carboxylic acids, esters or halides by reacting olefinically unsaturated compounds with carbon monoxide and water, or alcohol, or phenol, or a halogen halide, or by reacting acetylenically unsaturated compounds with carbon monoxide and a hydrogen halide, at elevated temperature and superatmospheric pressure in the presence of a palladium catalyst, the catalyst reused may be a solution obtained from the residue of the distillation and/or extraction of the acid constituents by alkaline reacting substances, of the reaction mixture, to which is added an organic phosphine. Phosphines mentioned are triarylphosphines and tricycloalkylphosphines. Examples describe the preparation of cyclododecadiene-(5,9) - carboxylic - (1) - carboxylic acid and the methyl and ethyl esters thereof and propionyl chloride in which the palladium catalyst is reused with the addition of organic phosphine.
