摘要：

The new N-chlorodimethylsilylmethyl-N'-trimethylsilyl-N,N'-propylene urea 5 was synthesized by trans-silylation reaction of N,N'-bis(trimethylsilyl)-N,N'-propylene urea 4 with CICH2SiMe2Cl. Mild hydrolysis of compound 5 results in the formation of N-[hydroxy(dimethyl)silylmethyl]-N,N'-propylene urea hydrochloride 6. The structure of the studied compounds in solution was determined by H-1, C-13 and Si-29 NMR spectroscopy and by X-ray analysis in the solid state. The results of these studies are indicative of pentacoordination of the silicon atoms in ureas S and 6. Compound 6 is a new example of poorly known protonated silanols with hypervalent silicon atom.
