The reactions of ZnBr(CF3)·2CH3CN with 1-morpholinocyclo-pentene and -hexene have been investigated and found to yield mixtures of two isomers of 1-morpholino-1-cyanomethyl-2-difluoromethyl-cyclopentane and -hexane, respectively. The interaction with methylene bases of nitrogen heterocycles leads to the formation of trimethinecyanine dyes. This reaction sequence includes the formation of two carbon-carbon
研究了ZnBr(CF 3)·2CH 3 CN与1-吗啉代环戊烯和-己烯的反应,并发现了1-吗啉代-1-氰基甲基-2-二氟甲基-环戊烷和-己烷的两种异构体的混合物,分别。与氮杂环的亚甲基碱基的相互作用导致形成三甲基花青染料。该反应顺序包括在一锅操作中形成两个碳-碳键。讨论了反应机理。
