Thioacetylenes 1 afford, upon treatment with p-toluenesulfonic acid in dichloromethane, (O,S)-ketene acetals 2 which can act as useful α-(organothio)vinyl carbocation equivalents, opening a novel route to functionalized vinylic sulfides.
硫代乙炔 1 在二氯甲烷中用对甲苯磺酸处理后,可生成 (O,S)- 酮乙炔 2,后者可作为有用的 δ-(有机硫)乙烯基碳位当量,为功能化乙烯基硫化物开辟了一条新途径。
