Halogenation of 1,1-diaryl alkenes

A variety of vinyl halides were prepared from reaction of 1,1-diarylalkenes with different halogenating agents (e.g., Selectfluor and N-halosuccinimide) with good yields under mild and base-free conditions. Synthesis of these molecules has been reported in the literature for being not easy to conduct. Among all the existing preparations of vinyl halide procedures, this protocol has the most facile and practical process.
