  Scheme of hydrolysis of five-coordinate chlorosilanes by X-ray diffraction data

  摘要：

  Hydrolysis of monochelate five-coordinate chlorosilanes MeC(O)N(Me)CH2SiMe2Cl (Ia), (LCH2SiMe2Cl)-C-7 (Ib), (LCH2SiMe2Cl)-C-8 (Ic), PhtImCH(2)SiMe(2)Cl (Id), MeC(O)N(Me)CH2SiMePhCl (IIa), and Im(5)CH(2)SiMePhCl (IIe), containing a monoanionic C,O-chelating ligand LCH2 [L is an amide, n-membered lactam (L (n) ), imide (Im (n) ), or phthalimide (PhtIm) residue]. The structures of the starting chlorides and their hydrolysis products were established by means of X-ray diffraction analysis. Based on experimental and published data, a general scheme of hydrolysis of mono-C,O-chelate chlorosilanes was suggested, including initial formation of silyloxonium chlorides III and subsequent formation of disiloxane dihydrochlorides IV.
