Strong Bronsted-base-catalyzed addition reactions of alkylazaarenes with vinylsilanes are reported. The reactions of alkylpyridines and their analogues with vinylsilanes proceed in moderate to high yields in the presence of catalytic amounts of LiTMP, LiCl, and MS 4A. This is a general method that can be applied to catalytic addition reactions of alkylazaarenes with vinylsilanes.
据报道,烷基氮杂芳烃与乙烯基硅烷的强布朗斯台德碱催化加成反应。在催化量的 LiTMP、LiCl 和 MS 4A 存在下,烷基吡啶及其类似物与乙烯基硅烷的反应以中等至高产率进行。这是一种通用方法,可用于烷基氮杂芳烃与乙烯基硅烷的催化加成反应。
