Abstract

New tris(4,4-dimethyl-2-oxazolinyl) phenylboratoiridium(I) scorpionate-type compounds [Ir(To(M))L-2] (L-2 = eta(4)-C8H12 and (CO)(2)) and electrophiles form adducts that contain a bidentate IrTo(M)-coordination and an N-electrophile interaction of the third oxazoline instead of the oxidative addition product. The adduct with lithium chloride gives a unique heterobimetallic Li-O-oxazoline-N-Ir bridging structure that has been identified through X-ray crystallography. Density functional theory calculations provide thermodynamic data, orbital symmetries, and orbital energies that explain the formation of the observed iridium( I) products. (C) 2009 Elsevier B. V.
