New phosphonic diamides and phosphinic amides of the 4,7,10-triaza-1λ 5-phosphabicyclo[5.3.0]decane and 4,7,10-triaza-1λ 5-phosphabicyclo[5.5.0]dodecane structures were prepared from bicyclic phosphoric triamides via the lithiation-induced N → C migration of phosphorus, followed by proton or haloalkane quenching.
