Abstract

Novel N-isopropyl-N',N'-dimethyl-N-(silylmethyl)ureas Me2NC(O)N(Pri)CH2SiMenX3–n (X = OEt, F; n = 0–2) were synthesized, and their structure was confirmed by 1H, 13C and 29Si NMR spectroscopy. According to NMR data, the silicon atom of the fluorosilanes (X = F) is pentacoordinated. The X-ray diffraction analysis of the (trifluorosilyl)methylcontaining urea showed that it exists as (O–Si) chelate with intramolecular dative bond C=O→Si (1.880 Å).
