7,11-(Butane-1,4-diyldioxydi-o-phenylenedimethylene)-6,6-dichloro-4,4-bis(pyrrolidin-1-yl)-2λ5,4λ5,6λ5-triphosphaza-1,3,5,7,11-pentaazaspiro[5.5]undeca-1,3,5-triene

Abstract

The title compound, C29H42Cl2N7O2P3, is a phosphazene derivative with a bulky substituent attached through a spiro junction with two pyrrolidine rings. The six-membered C3N2P ring has a chair conformation, while the phosphazene ring has a slight envelope conformation. The two N atoms in the C3N2P ring are likely to be stereogenic.
