Abstract

Reaction of (PNP)Li with TaF₅ produces pentagonalbipyramidal (PNP)TaF₄ (2). Alkylation of 2 with MeMgBr allows for the isolation of (PNP)TaMe₄ (3). (PNP)TaMe₄ (3) evolves thermally and/or photochemically into a bis(methylidene) complex (PNP)Ta(=CH₂) ₂ (4). The identity of the latter has been established by X-ray structural, NMR spectroscopic, and DFT computational studies. It does not appear that 4 possesses agostic interactions in solution.
