(E)-α-Selanylvinylzirconium and (E)-α-silylvinylzirconium complexes 2 were prepared conveniently via hydrozirconation of the alkynylselenides and the alkynylsilanes 1, respectively. Intermediates 2 were reacted with acyl chlorides 3 via Zr-Cu transmetallation with retention of the configuration to afford α-seleno or α-silyl α,β-unsaturated ketones 4 in good yield.
