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.
