A general method for the synthesis of vinylic chalcogenides by nucleophilic and Ni-catalyzed vinylic substitution on vinylic halides by phenyl chalcogenolates is described. The reactions were regio and stereoselective for the nickel catalyzed substitution, and mixture of isomers was observed for some examples in the thermal process in DMF.
描述了通过苯基硫属元素化物在乙烯基卤化物上通过亲核和Ni催化的乙烯基取代来合成乙烯基硫属元素化物的一般方法。对于镍催化的取代,该反应是区域性和立体选择性的,并且在DMF的热过程中的一些实例中观察到异构体的混合物。
