Abstract: New N-isopropyl-N',N'-diphenyl-N-(silylmethyl)ureas were obtained, and their structure was explored by ¹H, ¹³C, ²⁹Si NMR spectroscopy and X-ray analysis. These results have shown that N-isopropyl-N', N'-diphenyl-N-[(fluorosilyl)-methyl]ureas exist as (O–Si) chelates with intramolecular dative bond C=O→Si.

Keywords: N',N'-diphenyl-N-(silylmethyl)ureas, (O–Si) chelates, dative bond, pentacoordinate silicon atom, organosilicon compounds, NMR, X-ray.
