Palladium/copper (I) halide catalyzedcrosscouplings of (E)- and (Z)-1,2-difluorovinylstannanes with aryl iodides and vinyl halides proceeded at room temperature to stereospecificallygive 1,2-disubstituted-1,2-difluoroolefins and 1,2-difluoro or 1,2,3,4-tetrafluorosubstituted dienes in good to excellent yields.
