Synthesis of azadiphosphiridine complexes. Theoretical studies on ring formation, the P-to-P′ metal shift and the resulting nitrogen geometry

Abstract

Three azadiphosphiridine complexes were selectively synthesized, two of them revealing a W(CO)5 group P-to-P′ haptotropic shift and only one displayed a planar ring N atom. Theoretical studies on ring formation and geometry as well as on the P-to-P′ haptotropic shift are reported.
