A convenient method for the preparation of aryl trifluoromethylsulfones from the reactions of diaryliodonium salts with sodium trifluoromethanesulfinate in the presence of copper catalysts is described. Cuprous oxide in DMF was found to be the optimal catalyst for the reaction. The reaction conditions are tolerant of various functional groups as well as of various counteranions of the iodonium salt
描述了一种在铜催化剂存在下由二芳基碘鎓盐与三氟甲烷亚磺酸钠反应制备芳基三氟甲基砜的简便方法。发现DMF中的氧化亚铜是该反应的最佳催化剂。反应条件耐受碘鎓盐的各种官能团以及各种抗衡阴离子。通过以制备规模(88g)进行反应来证明该方法的合成效用。
