The reaction of vinylic grignard compounds with some thioketones

Vinylic organomagnesium compounds react with thiobenzophenone, thiopinacolone and thiopivalophenone to give first the organomagnesium compound resulting from the addition of the vinyl group on carbon. This compound rearranges, probably by a radical mechanism, to give an S-addition compound. Terpenic thioketones (thiocamphor and thiofenchone) do not react.
