Aromatic and aliphatic thioketones undergo hydrozirconation at room temperature with (C&) 2Zr (H) C1 to give sulfurzirconium compounds, &CHSZr (Cl)(C&&. Cleavage of the latter by bromine or N-bromosuccinimide affords sulfenyl bromides, acid chlorides give thioesters, methyloxalyl chloride gives a thiooxalate, methyl vinyl ketone [catalyzed by Ni (II)] reeulta in the formation of the &keto sulfide, and carbonylation followed by bromination in alcohol ...
