preparation of enamides (N-(alken-1-yl) amides) by means of the ‘long-distance' migration of the double bond in unsaturated amides in the presence of [Fe(CO)5] is described. The method is shown to be particularly useful for the isomerization of N-(but-3-enyl)amides, while, in the case of N-(pent-4-enyl) and N-(hex-5-enyl) amides the mixture of products was formed and the yield of the enamide was relatively
描述了一种通过[Fe(CO)5 ]存在下不饱和酰胺中双键的“长距离”迁移来制备酰胺(N-(烯-1-基)酰胺)的新方法。已表明该方法对于N-(丁-3-烯基)酰胺的异构化特别有用,而在N-(戊-4-烯基)和N-(六-5-烯基)酰胺的情况下,形成产物的混合物,并且烯酰胺的收率相对较低。
