, p. 132 - 140 (2001)
The X-ray crystal structure of a pentacoordinate silicon compound, 3, with a urea ligand shows partial Si-O bond formation and Si-Cl cleavage. The solution NMR parameters for the related series of compounds with different leaving groups provides structura

The aminosilanes MenSi(NRR')4-n (n = 2,3) with NRR' = ethylamino (NHEt), n-propylamino (NHnPr), sec-butylamino (NHsBu), n-octylamino (NHnOct), n-dodecylamino (NHnDodec), allylamino (NHAll), tert-butylamino (NHtBu), diethylamino (NEt2), and anilino (NHPh) were synthesized and their reactions with phenyl isocyanate were studied. In all cases of these silanes Me3SiNRR' and Me2Si(NRR')2 formal insertion of the -NCO group into their Si-N bonds was observed, i.e. formation of products with Si-N (rather than Si-O) bonds was found. In some cases, the products could be crystallized and their molecular structures have been elucidated with single-crystal X-ray diffraction analyses.
A distorted trigonal antiprismatic cationic silicon complex with ureato ligands: syntheses, crystal structures and solid state29Si NMR properties

Insertion of phenyl isocyanate into the Si-N bond of N-(tri methylsilyl)diethylamine yields the N'-silylated N,N-diethylN'-phenylurea 1, which undergoes transsilylation with SiCl4 to yield the C 3-symmetric cationic hexacoordinate si
