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.

A series of amides of the type RCONR′[CH2Si(CH3)2Cl] were prepared by the reaction of chloromethyldimethylchlorosilane with a series of N-alkyl, N-aryl, and trimethylsilylamides. The structure of the compound obtained from reaction with bis(trimethylsilyl)acetamide was previously determined by x-ray analysis and is used to rationalize the NMR and IR spectra of its 14N and 15SN isotopomers. The spectroscopic

A transsilylation reaction of bis[(N-methyl)acetamido]dimethylsilane with chloro(chloromethyl)(dimethyl)silane leads to the formation of two products: N-[chloro(dimethyl)silylmethyl]-N-methylacetamide (1) and N-[chloro(dimethyl)silyl]-N-methylacetamide (2).
