ChemInform Abstract: Chemistry of 4-Chloro-1,3,5,7-tetramethyl-1,3,5,7-tetraaza-4λ5-phosphaspiro(3.3)hepta# ne-2,6-dione; Crystal and Molecular Structure of a Chlorotetraaza- and of two Pentaazaphosphoranes.

ChemInform Abstract

The title compounds (III) prepared from (I) and (II) is converted into their derivatives (Va)-(Ve) according to the scheme. The new compounds are characterized by analysis, NMR, IR, and mass spectra. The strongly distorted, trigonal-bipyramidal structures of the parent compound (III) (space group Pbca, Z = 8) and their derivatives (Vc) ( P2₁/n, Z=4) and (Vd) (P1, Z=2) are determined by X-ray analysis.
