The synthesis of novel stibenium cations and their catalytic application in cyanosilylation of carbonyl compounds have been described. Treatment of chlorostibine LSbCl [L = 1,2-CH{N(CHBu)}] (2) with 1 equiv. of AgOTf and AgSbF resulted in the formation of donor free LSbOTf () and [LSb][SbF] (), respectively. Among these three compounds, 4 exhibits excellent catalytic activity towards the cyanosilylation of aldehydes and ketones.
新型锍鎓阳离子的合成及其在羰基化合物氰基硅烷化反应中的催化应用已被报道。用1当量的三氟甲磺酸银（AgOTf）和六氟锑酸银（AgSbF）处理氯代锑化合物LSbCl [L = 1,2-CH{N(CHBu)}] (2)，分别生成了无供体的LSbOTf () 和 [LSb][SbF] ()。在这三种化合物中，4对醛和酮的氰基硅烷化反应表现出优异的催化活性。
