Metallation-induced migration of phosphorus from nitrogen to carbon in 1-oxo-2,8-diphenyl-2,5,8-triaza-1λ5-phosphabicyclo[3.3.0]octane: unusual bonding parameters of the double migration product
Abstract
The title compound undergoes lithiation-induced rearrangement, first to a bicyclic phosphonic diamide, and next to a bicyclic phosphinic amide; for the latter product an unusually long phosphoryl bond was observed.
