Synthesis and reactivity of molybdenum and tungsten bis(dinitrogen) complexes supported by diphosphine chelates containing pendant amines

Abstract

Molybdenum and tungsten bis(dinitrogen) complexes of the formula M(N2)2(PNP)2 (M = Mo and W) and W(N2)2(dppe)(PNP), supported by diphosphine ligands containing a pendant amine of the formula (CH2PR2)2NR′ = PRNR′PR (R = Et, Ph; R′ = Me, Bn), have been prepared by Mg reduction of metal halides under an N2 atmosphere. The complexes have been characterized by NMR and IR spectroscopy, X-ray crystallography, and cyclic voltammetry. Reactivity of the target Mo and W bis(dinitrogen) compounds with CO results in the formation of dicarbonyl complexes.
