Abstract
Five pairs of isomeric cis- and trans- 2,4-bis(dialkylamino) -2,4-dichloro-6,6-difluorocyclotriphosphazenes (amines: dimethylamine, diethylamine, piperidine, morpholine, pyrrolidine) were prepared by fluorination, using KSO2F, of the corresponding 2,4-bis(dialkylamino) tetrachlorocyclotriphosphazenes. Mechanistic and other aspects of the reaction are discussed.
