摘要：

Chloroacyl halides are obtained under mild conditions by catalytic carbonylation in halogenated solvents of allylic halides or ethylene and allyl chloride mixtures under pressure of CO and anhydrous HCl in the presence of PdCl2; excellent selectivities for dichloroacyl and chloroacyl derivatives are achieved. Allyl chloride is partly consumed for the regeneration of palladium chloride. The product of oxidative addition of HCl to the oligomeric [Pd(CO)Cl](n) formed in situ by reaction of CO on PdCl2 is proposed as the first step towards the generation of the active species.
