Thioacetals were found to be effective precursors to generate and accumulate alkoxycarbenium ions based on direct and indirect cation pool methods. Alkoxycarbenium ions thus generated reacted with carbon nucleophiles such as allylsilanes and enol silyl ethers to give C–C bond formation products in good yields.
基于直接和间接阳离子池方法,发现硫缩醛是产生和积累烷氧基碳鎓离子的有效前体。这样产生的烷氧碳鎓离子与碳亲核试剂(例如烯丙基硅烷和烯醇甲硅烷基醚)反应,以高收率得到C–C键形成产物。
