The synthesis and reaction behavior of pentacoordinate hydrochlorosilanes LCH2SiRHCl (L- 2-piperidonyl ligand, R = Me, Ph, Bn) are described. The intramolecular O–Si and N–Si coordination is discussed on the basis of the NMR data. The strength of the O–Si coordinate bond is nearly the same for chelates 5, 6, 8 irrespective of the equatorial substituent R at the silicon atom. However, the nature of
描述了五配位氢氯硅烷LCH 2 SiRHCl(L-2-哌啶基配体,R = Me,Ph,Bn)的合成和反应行为。分子内的O-Si和N-Si配位在NMR数据的基础上进行了讨论。O型的Si配位键的强度几乎为螯合物同5,6,8,不论在硅原子上的赤道取代基R的。但是,R取代基的性质显着影响具有N-Si分子内键的配合物的稳定性。
