Photolysis of (FPNP)PdâEt in the presence of Et2Zn leads to the formation of (FPNP)PdâZnâPd(PNPF), the first example of a compound with a covalent PdâZn bond.

photochemical conversion to a dimeric (PNP)Pd−Pd(PNP) complex with a single Pd−Pd bond. Dissociation of the dimer into monomeric (PNP)Pd species is kinetically accessible thermally and photochemically. (PNP)Pd−Pd(PNP) reacts with ammonia, water, and dihydrogen by adding the H−X bond of the substrate (X = NH2, OH, H) across the Pd−Pd bond. For ammonia, this represents a rare example of conversion of NH3
