Abstract
Two aryl amino borinium cations derived from Cl(Mes)B-NR (NR = TMP, HMDS) faced divergent outcomes. As the HMDS-substituted one underwent methyl migration from silicon to boron transforming the putative borinium ion to a silylium ion, [Mes--TMP] can initiate cyanosilylation and catalyse hydrosilylation of ketones and aldehydes.
摘要
两个芳基氨基硼鎓阳离子衍生自 Cl(Mes)B-NR（NR = TMP，HMDS），呈现出不同的结果。HMDS 取代的那个经历了从硅到硼的甲基迁移，将假定的硼鎓离子转化为硅鎓离子，[Mes--TMP]可以引发氰基硅烷化反应，并催化酮和醛的硅氢化反应。
