Hydrozirconation of alkynes, followed by halogenation with N-halosuccinimide (N-bromo, IV-chloro) affords vinyl halides in reasonable yields (Hart et al, 1975). Vinyl cuprates, obtained by stereospecific addition of alkylcoppers to terminal alkynes, react with iodine in ether at —30° to give vinyl iodides (Normant et al, 1974). [Pg.143]
