在空气气氛下,用全氟烷烃亚磺酸钠(R f = CF 3,C 3 F 7,C 4 F 9,C 6 F 13,C 8 F 17)进行可见光诱导的未活化烯烃的自由基串联三氟甲基化/环化反应发达。一系列含有未活化烯烃部分的喹唑啉酮和全氟链烷磺酸钠与该转化相容,从而产生了各种全氟烷基取代的喹唑啉生物碱。值得注意的是,可以在没有任何金属催化剂,强氧化剂或外部光敏剂的情况下进行实验。

A newly developed CF3SO2Na-based trifluoromethylation of secondary amines has been disclosed, and the method has been successfully extended to the configuration of perfluoroalkyl amines using RfSO2Na, complementing the established synthesis strategy of trifluoromethyl amines. Advantages of the method include good functional group tolerance, mild conditions, and inexpensive or easy-to-handle materials

The present invention discloses a method for preparing a perfluoroalkyl sulfinate ester. The method includes reacting an α-carbonyldiazo compound and a sodium perfluoroalkyl sulfinate, in an organic solvent, in the presence of anhydrous copper acetate as an optimal catalyst and tert-butyl hydroperoxide (TBHP) as a green oxidant, to obtain the perfluoroalkyl sulfinate ester. Compared to the prior art, the present method has the advantages of a wide range of reaction substrates, a short reaction time, a high reaction yield, and mild reaction conditions. The reaction does not require pre-activation of sodium perfluoroalkyl sulfinate, which can participate in the reaction directly, making reaction operations simple. The present method uses TBHP as a green oxidant and produces tert-butanol and water after reaction. Moreover, the present method avoids using a bromide or a chloride as a reaction material, and thus avoids formation of a large amount of a halide salt.
