Diastereoselective formation of a dipalladium(I) complex supported by a bridging tetradentate ligand, and oxidative addition of RS-H across a phosphine-bridged Pd(I)-Pd(I) bond.
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(mu-N,P,P,N-dmapm), which, unlike the well-known Pd2X2(mu-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.
