Diastereoselective formation of a dipalladium(i) complex supported by a bridging tetradentate ligand, and oxidative addition of RS–H across a phosphine-bridged PdI–PdI bond

Abstract

The ligand CH₂(P(o-C₆H₄NMe₂)₂)₂ (dmapm) gives access to the first example of a dipalladium(I) complex supported by a tetradentate ligand, Pd₂Cl₂(μ-N,P,P,N-dmapm), which, unlike the well-known Pd₂X₂(μ-dppm)₂ complexes (X = halide, dppm = bis(diphenylphosphino)methane), reacts with thiols to give addition of RS–H across a phosphine-bridged Pd–Pd bond.
