A series of zero-valent Pd complexes featuring PMP ligands (M = LiI, CuI, ZnII) is reported. An excellent activity in chemoselective CO2 hydrosilylation producing silyl formate is observed (TOF1/2 = 3000 h−1).

A series of [(PMP)Rh(CO)Cl] complexes was synthesised and the impact of the metalloligands Cu, Li and Zn on the CO stretching band was analysed.

SummaryThe reaction of CpPd(η3-C3H5) with the new diphosphinoborane ligand derivative (o-PCy2-C6H4)2BPh Cy DPB Ph affords the T-shape complex (Cy DPB Ph)Pd(0) 9, which was characterized by X-ray analysis.
