Indium(III) bromide is found to catalyze efficiently the hydrothiolation of unactivated alkynes with various thiols under mild conditions to produce the corresponding dithioacetals in excellent yields. However, addition of aromatic thiols on aromatic alkynes gave the β-vinyl sulfides in high yields. This new procedure offers significant advantages such as high conversions, short reaction times, and
发现溴化铟 (III) 在温和条件下有效催化未活化炔烃与各种硫醇的氢硫醇化反应,以优异的产率生产相应的二硫代缩醛。然而,在芳香炔烃上加入芳香硫醇以高产率得到 β-乙烯基硫化物。这种新方法具有显着的优势,例如转化率高、反应时间短和操作简单。
