Synthesis and Characterization of New Trifunctional Tetraorganylsilanes of the Formula Types MeSi(CH2X)3, MeSi(CH2X)2CH2X′, and MeSi(CH2X)(CH2X′)CH2X′′

A series of novel trifunctional tetraorganylsilanes of the general formula types MeSi(CH2X)3 (X = I (2), OAc (3), OH (4), Br (5), (4-methylphenyl)sulfonyloxy (6), phthalimido (7), NH2·HBr (8·3HBr)), MeSi(CH2X)2CH2X′ (X = SH, X′ = OH (9); X = Cl, X′ = OAc (11); X = SAc, X′ = OAc (12)), and MeSi(CH2X)(CH2X′)CH2X′′ (X = Cl, X′ = OAc, X′′ = SAc (rac-13); X = phthalimido, X′ = OAc, X′′ = SAc (rac-14); X = N3, X′ = OAc, X′′ = SAc (rac-15)) was synthesized, starting from MeSi(CH2Cl)3 (1). All the compounds synthesized was characterized by elemental analyses (C, H, N, S) and NMR studies (1H, 13C, 15N (rac-15 only), 29Si). In addition, compounds 4 and 6 were structurally characterized by single-crystal X-ray diffraction. The title compounds are claimed to be versatile starting materials for the synthesis of a variety of novel C-functional organosilicon compounds.
