COORDINATION CHEMISTRY OF PHOSPHORUS(III) AND PHOSPHORUS(V) HYDRAZIDES

The main group chemistry of phosphorus(III) and phosphorus(V) hydrazides is described. Specifically, the synthesis and characterization of several phosphorus(III) hydrazides of the general formula: R(2)P-N(R')-N(R')-PR(2) and phosphorus(V) hydrazides of the type: R(2)P(E)(NMeNH(2)), RP(E)(NMeNH(2))(2), and P(E)(NMeNH(2))(3)(E=S, O) and their Schiff base adducts are summarized. The transition metal chemistry of phosphorus(III) hydrazides with the early and late transition metals (e.g. Mo-0, W-0, Rh-I, Pd-II, and Pt-II) reveal mononuclear coordination interaction of the two phosphine centres with the metal centres. The coordination chemistry of phosphorus(V) hydrazides demonstrates the versatility of their banding with the transition metals.
