The phosphorylation of a series of diaminopyridines (2,3-, 3,4-, 2,5- and 2,6-diaminopyridine), with various molecular equivalents of chlorodiphenylphosphine in the presence of TEA has been studied. Notably, phosphorylation of 2,3- and 3,4-diaminopyridine affords compounds with diphosphinoamine (P-N-P) and iminobiphosphine (N=P-P) entities co-existing in the same molecule. Phosphorylations of 2,5- and 2,6-diaminopyridine afford compounds containing only diphosphinoamine units. The solid-state structure of three compounds has been determined including the first example of a crystallographically characterized compound containing both a diphosphinoamine group and an iminobiphosphine group in the same structure. The key factors that govern the formation of P-N-P vs. N=P-P moieties have been elucidated and a molecule containing both entities has been isolated. Copyright

A series of monovalent Re complexes, mer-[Re{κ3-2,6-(Ph2PNH)2NC5H3}(CO)3]+, cis-[Re{κ3-2,6-(Ph2PNMe)2NC5H3}(CO)2Cl], and mer-[Re{κ3-2,6-(Ph2PNMe)2NC5H3}(CO)3]+ supported by neutral “PN3P” ligands have been synthesized by addition of pincer ligand to Re(CO)5X (X = Cl, Br). The products were characterized by multinuclear NMR and single crystal X-ray diffraction studies and showed a dependence on the identity of the halo ligand in starting material and on the substitution pattern of the pincer ligand. The formation of the mer-Re(CO)3 core geometry and the autoionization of halide ligand in the majority of these species is in marked contrast to the bulk of the literature on the substitution chemistry of Re(I) carbonyl halides.
