Synthesis and inner-sphere hydrophosphorylation of (η1-N)-N-benzyl-N-(1,3-dimethylbut-2-enylidene)amine-(dicarbonyl)(1,3,5-triorganyl-1,3,5-triazacyclohexane) molybdenum(0) and -tungsten(0)

Abstract

Complexes of group VIb metals (Mo and W) has been prepared with N-benzyl-(3-methylbut-2-enylidene)amine, where the latter is coordinated with the dicarbonyl(1,3,5-triorganyl-1,3,5-triazacyclohexane)-metal(0) fragment exclusively through the lone electron pair of the imine nitrogen atom. The reactions of the synthesized metal complexes with diethyl phosphite in various conditions always involved the addition of the phosphite across the С=N bond to form, depending on the conditions, aminophosphonates or their inner-sphere rearrangement products amidophosphates. Both organophosphorus compounds remain in the coordination sphere of the transition metal complex.
