Abstract

Treatment of 6-R-2-(Me₃SiCH₂)C₅H ₃N (R = H or Me) with nBuLi in diethyl ether affords the dimeric lithium complexes [{2-(6-R-Pyr)(Me₃Si}CHLi-OEt₂] ₂= pyridine, C₅H₃N) in high yields. In these complexes, the two anionic ligands have different bonding modes. These complexes easily undergo insertion reactions with nitriles to form six-membered cyclic dimeric complexes in good yields. Further transmotalaUons of the six-membered cyclic complexes with CuCl, SnCl₄, or CoCl₂ allow the formation of new metal complexes that maintain the frameworks of the six-membered melallacycles. All complexes represented above were fully characterized by methods including single-crystal X-ray crystallography.
