α,α’-Disubstituted styrenes undergo a difluorination-rearrangement reaction with fluoro-benzoiodoxole reagent 1. The reaction is catalyzed by Pd(MeCN)4(BF4)2 and Cu(MeCN)4PF6. We have studied the rearrangement of α,α’-diaryl substitutedstyrenes, in which the aryl groups have different electronic character. In the case of α-aryl, α’-alkyl substitutedstyrenes, the aryl substituent has a higher migratory
