Vinyl iodides have been treated with various copper(I) derivatives (aryl- and alkyl-copper derivatives, copper(I) chloride, cyanide, bromide, thiolate) and found to undergo substitution at carbon with retention of configuration. Copper(II) carboxylates give much better yields of enol esters than the corresponding copper(I) salts. A four centre mechanism accounts best for the results.
乙烯基碘已用各种铜(I)衍生物(芳基和烷基铜衍生物,氯化铜(I),氰化物,溴化物,硫醇盐)处理过,并发现在碳上被取代并保留了构型。铜(II)的羧酸盐,得到烯醇酯的比相应的铜(I)盐更好的产率。四个中心的机制最能说明结果。
