Abstract

In the presence of a catalytic amount of (Ph3P)AuNO3 and phthalimide, the addition of toluenesulfonic acid or methanesulfonic acid to alkynes has been shown to proceed and gives vinyl tosylates and vinyl mesylates in good yields and regioselectivity.

摘要

在催化量的(三苯基膦)金(III)硝酸盐和邻苯二甲酰亚胺存在下，向炔烃中加入甲苯磺酸或甲磺酸已被证明可以进行反应，并以良好的产率和区域选择性得到乙烯基甲苯磺酸酯和乙烯基甲磺酸酯。
