N-Phosphoryl-2-oxo-1,2-azaphospholanes: First Example of Cyclic O,O-Bidentate Ligands with the P-N-P Backbone
摘要:
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 (mu 2-peroxo)-bridged uranium complexes, depending on both the ligand and metal nature.

to look for concise and efficient methods for the synthesis of this unit. In this work, a new strategy was developed in which a one-pot synthesis of N-phosphorylated amides was achieved by a three-component reaction with carboxylic acids, phosphorus chlorides and azides under mild reaction conditions. To our knowledge, this is the first study in which this framework was constructed through a multicomponent
Facile One-Pot Synthesis and X-ray Characterization of N-(Thio)phosphoryl-2-oxo-1,2-azaphospholanes: First Example of Cyclic O,O- and O,S-Bidentate Ligands with the P-N-P Backbone
A convenient one-pot synthesis of N-phosphoryl- and N-thiophosphoryl-2-oxo-1,2-azaphospholanes was developed, starting from commercially available or simple-to-prepare phosphorus(III) acid chlorides and (3-bromopropyl)amine hydrobromide. The method is based on the intramolecular Arbuzov reaction of bis-phosphorus(III)-substituted N-(3-bromopropyl)amines generated in turn by double phosphorylation of
