Abstract

The silicon atom in LSiCl or LSiMes (L = PhC(NBu), Mes = 2,4,6-MeCH) inserts into the B-X bond of RBX (R = Ph, Mes, N(SiMe); X = Cl, Br), which is followed by the migration of the amidinate ligand and the halide atom. By this way, LB(R)SiCl (R = Ph, ; Mes, ; N(SiMe), ) and LB(R)SiXMes (R = Ph, X = Cl, ; R = Mes, X = Cl, ; R = Mes, X = Br, ) were obtained. Furthermore, a silylene-borane adduct LClSi → BPhCl () was obtained as an intermediate in the formation of compound . Compounds - are rare examples of borylhalosilanes.

摘要

在LSiCl或LSiMes（L = PhC(NBu)，Mes = 2,4,6-MeCH）中的硅原子插入到RBX（R = Ph、Mes、N(SiMe)；X = Cl、Br）的B-X键中，随后脒基配体和卤原子发生迁移。通过这种方式，得到了LB(R)SiCl（R = Ph、；Mes、；N(SiMe)、）和LB(R)SiXMes（R = Ph，X = Cl、；R = Mes，X = Cl、；R = Mes，X = Br、）。此外，还得到了一种硅烯 - 硼烷加合物LClSi→BPhCl（）作为化合物形成过程中的中间体。化合物 - 是硼基卤代硅烷的罕见例子。
