iminium ion promoter from alpha-amino nitriles, is an efficient additive in the Bruylants reaction involving vinylic Grignards. Improved yields of allylic amines were obtained when the starting alpha-amino nitrile was treated with this silver salt prior to its reaction with the vinylic Grignard. This improvement was not observed in the case of acetylenic Grignards. The reactivity of other vinyl organometallics
四氟硼酸银,用作α-氨基腈的亚胺离子促进剂,在涉及乙烯基格氏试剂的Bruylants反应中是一种有效的添加剂。在这种银盐与乙烯基格氏试剂反应之前,用这种银盐处理起始的α-氨基腈,可以提高烯丙基胺的收率。在炔属格氏试剂中未观察到这种改善。简要检查了其他乙烯基有机金属(M = Zn,Li,Al,Cu,Si)的反应性。
