Hydrozirconation of phospha-alkenes and phosphaimines. Evidence for the formation of P–C–Zr and P–N–Zr three-membered rings

Abstract

Addition of bis(η-cyclopentadienyi)zirconium hydride (Cp2ZrHCl) to phospha-alkenes and phosphaimines leads either to a functionalized bis(η-cyclopentadienyl)zirconium phosphirane and azaphosphirane or to a protonated dico-ordinated phosphorus species.
