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.
