Useful triheteroarylmethanes were prepared by the double Friedel–Crafts reaction of a wide variety of aromatic N-tosyl imines with furan, thiophene, and pyrrole in the presence of Cu(OTf)2 and Montmorillonite K-10 clay catalysts.
有用的三杂芳基甲烷是在Cu(OTf)2和蒙脱土K-10粘土催化剂存在下,通过多种芳族N-甲苯磺酰基亚胺与呋喃,噻吩和吡咯的双重Friedel-Crafts反应制备的。
