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.
在催化量的(Ph3P)AuNO3和邻苯二甲酰亚胺的存在下,将氨基甲烷磺酸或甲苯磺酸加入到炔烃中,已显示能够进行反应,并在良好的产率和区域选择性下生成乙烯基磺酸酯和乙烯基甲磺酸酯。
