Palladium/copper (I) halide catalyzed cross couplings of (E)- and (Z)-1,2-difluorovinylstannanes with aryl iodides and vinyl halides proceeded at room temperature to stereospecifically give 1,2-disubstituted-1,2-difluoroolefins and 1,2-difluoro or 1,2,3,4-tetrafluorosubstituted dienes in good to excellent yields.
钯/铜(I)卤化物催化(E)-和(Z)-1,2-二氟乙烯基锡与芳基碘化物和乙烯基卤化物的交叉偶联在室温下进行,立体定向生成1,2-二取代-1,2-二氟烯烃和1,2-二氟或1,2,3,4-四氟取代的二烯,收率良好至优异。
