N-Phosphoryl-2-oxo-1,2-azaphospholanes: First Example of Cyclic O,O-Bidentate Ligands with the P-N-P Backbone

Abstract

A convenient one-pot synthesis of N-phosphoryl-2-oxo-1,2-azaphospholanes was developed starting from commercially available or simple-to-prepare phosphorus (III) acid chlorides and 3-bromopropylamine. The compounds readily form complexes with f-elements of ML, ML₂, and M₂L₃ composition including (μ₂-peroxo)-bridged uranium complexes, depending on both the ligand and metal nature.
