✦ Synopsis
We have found that-olefin-palladium chloride complex is carbonylated to give 8-chloro acyl chloride.* In addition, ve have found that metallic palladium ia a versatile catalyst for carbonylation of various olefinic compounds. For example, simple olafins and nonconjugated cyuloolefins4 can be converted ir ethanol into saturated esters', and allylic compounds5 and conjugated dienek formp,runsaturated eaters. In these catalytic oarbonylations, the presence of metallic palladium and hydrogen chloride was found to be essential, and the formation of acyl-palladium complex as an intermediate is assumed by analogy with the mecha-
