Abstract

The synthesis and reactivity toward cis-[Pt(C6F5)2(THF)2] of several alkynylphosphine d8 complexes, [Pt(C6F5)(PPh2C⋮CPh)3](CF3SO3), 1, [M(COD)(PPh2C⋮CPh)2](ClO4) (M = Rh, 2, and Ir, 3), and [Pt(o-C6H4E2)(PPh2C⋮CPh)2] (E = O, 6, and S, 7), are reported. Whereas 1 gives rise to the diinserted product 8, which evolves in solution to the bis(diphenylphosphine)naphthalene-based mononuclear complex 9, analogous reactions with 2 or 3 give mixtures of products. The reactions with 6 or 7 afford binuclear heterobridged (μ-κE-o-C6H4E2)/(μ-κP:η2-PPh2C⋮CPh) 11 and 12 or trinuclear (μ3-κ2EE‘-o-C6H4E2)/(μ-κP:η2-PPh2C⋮CPh)2 13 and 14 complexes.
