The addition of 2-mercaptobenzoxazole or 2-mercaptobenzothiazole to trimethoxy(vinyl)silane was studied. The thiol-ene reaction leads to previously unknown carbofunctional (trimethoxysilyl)ethyl derivatives of 2-mercaptobenzazoles C₆H₄N(Y)CS(CH₂)₂Si(OMe)₃ (Y = O, S) with anti-Markovnikov orientation. The proposed mechanism is confirmed by EPR spectroscopy and quantum chemical calculations.

在无溶剂和无催化剂的条件下，将2-巯基苯并恶唑和2-巯基苯并噻唑反马氏添加到三甲氧基（乙烯基）硅烷中

研究了将2-巯基苯并恶唑或2-巯基苯并噻唑添加到三甲氧基（乙烯基）硅烷中。硫醇-烯反应导致2-巯基苯并恶唑的碳官能（三甲氧基甲硅烷基）乙基衍生物先前未知，具有反马氏力取向的C ₆ H ₄ N（Y）CS（CH ₂）₂ Si（OMe）₃（Y = O，S） 。所提出的机理已通过EPR光谱学和量子化学计算得到了证实。
