In a search for an unambiguous example of the vinylic Sml route, several vinyl bromides and iodides were reacted mostly with-CH2COCMe3, and sometimes with-CH&OPh,-CH (Me) COEt, and (Et0) zPO-ions, under Fe2+-or photostimulation in MezSO. Vinyl halides having vinylic hydrogens, such as P-bromostyrene, gave acetylenic products, eg, phenylacetylene or a tertiary PhCZC-substituted alcohol, whereas vinyl halides with allylic hydrogens, such ...
