Abstract
The reaction of N-methyl-N-trimethylsilylacetamide with silanes ClCH2SiR1R2Cl (R1, R2 = H, Me; H, Ph; Ph2) leads to the formation of (O→Si) chelate compounds with pentacoordinate silicon: N-[chloro(methyl)-silyl]methyl-, N-[chloro(phenyl)silyl]methyl-, and N-[chloro(diphenyl)silyl]methyl-N-methylacetamides. From the data of multinuclear NMR spectroscopy, the intermediates of the reaction of N-methyl-N-trimethylsilylacetamide with ClCH2SiPhHCl and ClCH2SiPh2Cl are stable in CDCl3 solution at room temperature during several days and slowly rearrange to the final (O–Si) chelate compounds.
