In the absence of any additional catalysts, the reactions of (CF(3)SO)(2)CH(2), aldehydes, and 1,3-dienes gave gem-bis(triflyl)cyclohexenes in excellent yields with high regioselectivity. gem-Bis(triflyl)cyclohexene products can be easily converted to the corresponding aryl trifluoromethyl sulfones.
在没有任何其他催化剂的情况下,(CF(3)SO)(2)CH(2)、醛和 1,3-二烯的反应以优异的收率和高区域选择性得到了偕二(三氟甲基)环己烯。偕二(三氟甲基)环己烯产物可以很容易地转化为相应的芳基三氟甲基砜。
