(CH3)2Sn(CHCH2)2·2 CuCl, and (C4H9)Sn(CHCH2)2·2 CuCl are prepared by allowing the neat vinylmetallic to react with copper(I) chloride. The new π-complexes are characterized by elemental analysis and by IR and NMR spectroscopy. A bonding schme is proposed to explain the unusual liability of these complexes.
