Reactions of the terminal rhenium acetylide complex Re(η5-C5H5)(NO)(PPh3)(CCH) and butyllithium; generation, alkylation and stannylation of lithiocarbide complexes of the formula Re(η5-C5H4)(NO)(PPh3)(CCLi)(X = H, Li)

Abstract

The title reaction gives, depending upon stoichiometry and conditions, Re(η⁵-C₅H₅)(NO)(PPh₃)(CCLi) and Re(η⁵-C₅H₄Li)(NO)(PPh₃)(CCLi); the first transition metal–alkali metal carbide complexes which are in turn derivatized by carbon and metal electrophiles.
