Abstract tert-Butyl vinyl ether (1) reacts with p-TolSCl to give 2-tert-butoxy-2-chloroethyl p-tolyl sulfide (2). In the presence of SnCl4, 2 reacts with silyl enol ethers, allyltrimethylsilane, and vinyl ethers to form a C-C bond. In the case of vinyl ethers, the reaction proceeds through the formation of the 5-membered sulfonium salt intermediate which in turn can react with H2O, TMSCN, allyltrimethylsilane
摘要 叔丁基乙烯基醚 (1) 与 p-TolSCl 反应生成 2-叔丁氧基-2-氯乙基对甲苯基硫化物 (2)。在 SnCl4 存在下,2 与甲硅烷基烯醇醚、烯丙基三甲基硅烷和乙烯基醚反应形成 CC 键。在乙烯基醚的情况下,反应通过形成 5 元锍盐中间体而进行,中间体又可以与 H2O、TMSCN、烯丙基三甲基硅烷和格氏试剂反应。
