PH-functional phosphanes containing a 2-pyridyl substituent in α- or β-position to phosphorus, e.g. 2-C5H4N-n-PRH (R = H, iPr, tBu, Ph; n = 1, 2) have been obtained.The reactivity of the PH-groups can be employed for the synthesis of tridentate NPN-hybrid donors, 2PR (R = H, Ph).The phosphanes 2-C5H4N-n-PRH behave as monodentate ligands in transition metal complexes and form labile chelate ring systems.They may bridge metal-metal bonds to form seven membered ring systems, e.g.Mo2PC3N.The coordination of the N-donor of the ligands 2-C5H4N- n-PRH to a transition metal atom is indicated by a lowfield shift and a small (31)P-(13)C-splitting of the 13C NMR signal of carbon atom 6 in the pyridin ring system. - 2-Pyridyl Substituent, Reactions at PH-Functions, Chelate Complexes, Ligand Replacement, 13C NMR Spectra
