The first highly efficient double Friedel–Crafts reaction of N-tosyl imines with anisole, phenol, thioanisole and analogues has been developed to produce the corresponding symmetric diarylmethanes and triarylmethanes with high regioselectivity in the presence of a catalytic amount of Bi2(SO4)3–TMSCl at room temperature.
首次开发了一种高效的N-甲苯磺酰亚胺与茴香醚、苯酚、硫代茴香醚及其类似物的双弗里德尔-克拉夫茨反应,在室温下,使用催化量的Bi2(SO4)3-TMSCl,以高区域选择性制备相应的对称二芳基甲烷和三芳基甲烷。
