Description
Summary:Hydrolysis of monochelate five-coordinate chlorosilanes MeC(O)N(Me)CH 2 SiMe 2 Cl ( Ia ), L 7 CH 2 SiMe 2 Cl ( Ib ), L 8 CH 2 SiMe 2 Cl ( Ic ), PhtImCH 2 SiMe 2 Cl ( Id ), MeC(O)N(Me)CH 2 SiMePhCl ( IIa ), and Im 5 CH 2 SiMePhCl ( IIe ), containing a monoanionic C,O-chelating ligand LCH 2 [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 .
