Abstract
The reaction of dichloromethylphenylsilane with tert-butanol in the presence of a hydrogen chloride acceptor gave tert-butoxychloromethylphenylsilane. The product is stable at room temperature for a week, undergoing disproportionation upon more prolonged storage. Its reaction with 2-substituted ethanols XCH2CH2OH (X = Cl, MeNH, PhCH2N, PhN) in the presence of bases gives the corresponding polyfunctional silanes MePhSi(OBut)(OCH2CH2X). Alkylation of such N-substituted derivatives with (chloromethyl)triethoxysilane results in polyfunctional α-silyl amines MePhSi(OBut)OCH2CH2N(R)CH2Si(OEt)3 (R = Me, Bn). The structures of all synthesized compounds were confirmed by IR and multinuclear NMR spectroscopy.
