What is Diphosphatetraazacycloogtatetraenes. I. Syntheses and properties about?

A series of novel eight-membered heterocycles containing 1,3 and 1,5 phosphorus arrangements were synthesized. The 1,5\_diphosphatetraazacyclooctatetraenes were obtained from the interaction of pedluoroalkyletheramidines and trichlorophosphoranes; the 1, d-isomers were prepared from perfluoroalkyletherimidoylamidines and imido-tetraphenyl-diphosphinic acid trichloride . The two series of cyclooctatetraenes exhibited infrared spectral absorptions characteristic for the given positional arrangement. However, electron impact fragmentation patterns of the two ring systems were closely comparable. Both series of compounds exhibited characteristic absorptions in the 6-6.51-1 region. Only one band was observed for the 'symmetrical' compounds in agreement with the behavior of the triazines and phospha-s-triazines. However, two distinct bands were observed for the 'unsymmetrical' analogues.
