The three‐component free‐radical carbo‐alkenylation of electron‐rich olefins has been studied, varying the substitution pattern in the alkene, in the radical precursor and in the final acceptor. New vinylsulfones were also prepared and their reactivity investigated. The scope and limitations of the process was established, and the reaction mechanism clarified using selected dienes as radical clocks
已经研究了富电子烯烃的三组分自由基碳烯基化反应,改变了烯烃,自由基前体和最终受体中的取代方式。还制备了新的乙烯基砜,并研究了它们的反应性。确定了该方法的范围和局限性,并使用选定的二烯作为自由基钟阐明了反应机理。因此,人们认识到,已释放的磺酰基可逆地加到烯烃上是一个重要事件,在使用这种多组分碳烯基化反应时不应忽视。
