                                    A variety of new chlorosilanes were synthesized by the selective thiol-ene reactions of various thiols (ethanethiol, 1,2-ethanedithiol, benzenethiol, and tetrakis(2-sulfanylethyl)silicate) with chlorovinylsilanes (chlorodimethylvinylsilane, dichloromethylvinylsilane, and trichlorovinylsilane). No silylthioester products were observed. All products were obtained in quantitatime or near quantitative yields and were characterized using multinuclear NMR (H-1, C-13, Si-29) spectroscopy. The products required no further purification. An example is presented which highlights the potential use of these compounds for future applications. (C) 2014 Elsevier Ltd. All rights reserved.
