Abstract
The reactions of aminocyclotriphosphazatrienes with dihalogenotriphenyl- and trihalogenodiphenyl-phosphoranes (the Kirsanov reaction) in carbon tetrachloride, chloroform, and benzene have been investigated. By means of these reactions, phosphazen-1′-yl groups can be attached to cyclotriphosphazatriene rings. The course of the reaction is altered by both the nature of the halogen atoms, and the number of phenyl groups in the phosphorane. The possible mechanisms of these reactions are discussed and their application to the synthesis of a compound obtained by a ring-contraction reaction of octachlorocyclotetraphosphazatetraene with a Grignard reagent is described.Keywords
