Formation of Gold(III) Alkyls from Gold Alkoxide Complexes.

ABSTRACT: The gold(III) methoxide complex (C^∧N^∧C)AuOMe (1) reacts with tris(p-tolyl)phosphine in benzene at room temperature under O abstraction to give the methylgold product (C^∧N^∧C)AuMe (2) together with O=P(p-tol)₃ ((C^∧N^∧C) = [2,6-(C₆H₃^t Bu-4)₂pyridine]^2-). Calculations show that this reaction is energetically favorable (ΔG = -32.3 kcal mol^-1). The side products in this reaction, the Au(II) complex [Au(C^∧N^∧C)]₂ (3) and the phosphorane (p-tol)₃P(OMe)₂, suggest that at least two reaction pathways may operate, including one involving (C^∧N<
