Vinyl-halides-reaction, in organic chemistry, a vinyl halide is a compound with the formula ch 2 =chx (x = halide).the term vinyl is often used to describe any alkenyl group. for this reason, alkenyl halides with the formula rch=chx are sometimes called vinyl halides. from the perspective of applications, the dominant member of this class of compounds is vinyl chloride, which is produced on the scale of millions of ....

Organic halides will couple with ethyne in the presence of a palladium catalyst and base to give disubstituted alkynes (equation (103)) < 75jom(93)253, 75jom(93)259, 75tl4467 >. as the reaction does not proceed in the absence of base, attack of acetylide ion on an intermediate organopalladium halide is implicated.
