Iminophosphine cycloaddition reactions of a diazaphosphoniaaluminatacyclobutane and a novel intramolecular phosphiridine P -> P coordination
Reactions of 1,3-bis(trimethylsilyl)-4,4-dichloro-1,3,2 lambda(2),4-diazaphosphoniaaluminatacyclobutane with Cl- or CN-give phosphazane derivatives, and the cycloaddition (cycloexpansion) is mimicked by the reversible reaction with (Me3Si)(2)NPNSiMe3 which gives an azadiphosphiridine derivative as a result of intramolecular cross-ring P-->P coordination.
