Abstract
A series of multifunctional (chloromethyl)silanes have been synthesized: Cl2Si(CH2Cl)2 (1), (MeO)2Si(CH2Cl)2 (2), tris(chloromethyl)(2,4,6-trimethoxyphenyl)silane (3), ClSi(CH2Cl)3 (4), MeOSi(CH2Cl)3 (5), Si(CH2Cl)4 (6), and ClCH2CH2Si(CH2Cl)3 (7). The synthesis of these compounds is based on coupling reactions between (chloromethyl)lithium, generated in situ from bromochloromethane and n-butyllithium in tetrahydrofuran, and chlorosilanes. Compounds 1−7 were characterized by NMR studies (1H, 13C, 29Si) and elemental analyses, and 3 and 6 were additionally studied by single-crystal X-ray diffraction. Silanes with more than one SiCH2Cl moiety and compounds of this type with additional Si-functional groups are of great interest for synthetic organosilicon chemistry.
