N-Acyliminium ion pools, which are generated from α-silyl carbamates, were found to react with a variety of alkenes and alkynes to give the corresponding cycloadducts. The reaction with styrene derivatives gave rise to the formation of a significant amount of polymeric products. The use of micromixing, however, resulted in a significant increase in the yield of the cycloadduct at the expense of the
发现由 α-甲硅烷基氨基甲酸酯生成的 N-Acyliminium 离子池与各种烯烃和炔烃反应生成相应的环加合物。与苯乙烯衍生物的反应导致形成大量聚合产物。然而,微混合的使用导致环加合物产率的显着增加,但以聚合物为代价。机理研究表明,对于烷基取代的烯烃,协调机制似乎最有可能,而对于芳基取代的烯烃,逐步机制似乎是合理的。
