A three-step synthesis for the bifunctional ligand (phenyl)(pyridin-2- ylmethyl)phosphinodithioic acid, [2-C5H4N]CH 2P(S)(SH)(Ph) (3-H), was developed. The molecule was characterized by spectroscopic methods, and single cr

New, functionalised phosphines with an OPN donor set which are potentially capable of square planar co-ordination were synthesized by stepwise introduction of the oxygen and nitrogen functional substituents to phosphorus. The secondary phosphines (phenyl)(tetrahydrofurfuryl)phosphine, 1, and [2-(l, 3-dioxolan-2-yl)ethyl](phenyl)phosphine, 2, were first prepared before the introduction of the nitrogen donor substituents. The OPN phosphines (phenyl)(D')(D2)phosphine {D1 = tetrahydrofurfuryl, D2 = 2-pyridylmethyl or pyridyl; D1 = 2-(l, 3-dioxolan-2-yl)ethyI, D2 = 2-pyridylmethyl}, 3-5, were obtained. This approach was not appropriate for the preparation of an OPN ligand with an ester functionality. Therefore the synthesis of methyl 3-[(phenyl)(2-pyridylmethyl)phosphino]propanoate, 7, was achieved via a radical induced coupling of methyl acrylate to (phenyl)(2-pyridylmethyl)phosphine 6. All new ligands, 1-5, 7, were characterised by 'H, "C and 3IP NMR spectroscopy. The methods developed allowed the ligands to be synthesized in high yields and purity such that further purification was generally unnecessary for subsequent applications.

PH-Functional Phosphanes with 2-Pyridyl Substituents in α- or β-Position 2-C5H4N-n-PRH (R = H, iPr, tBu, Ph, 2-C5H4N-n; n = 1, 2)

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
