Abstract

248ChemInform Abstract Dehydrochlorination of the phosphorinane (I) gives the oligomeric benzoxazaphosphorines (II). (I) is regained from (II) on treatment with hydrogen chloride. Coupling of (II) with diethylamine or phosphorus trichloride yields the phosphorinanes (III) and (IV) respectively.
