The syntheses of pyrazole amine substituted cyclotriphosphazenes: Spectroscopic and crystallographic characterizations

Abstract

The aminolysis reactions of hexachlorocyclotriphosphazene, N3P3Cl6(1a) and di-spirodioxy cyclotriphosphazene derivative N3P3Cl2[OCH2(CF2)(2)CH2O](2)(1b) with 1-benzyl-1H-pyrazol-3-amine (2) were investigated. Two new pyrazole amine substituted cyclotriphosphazene derivatives (3a,b) were obtained. Both compounds (3a,b) have been characterized by elemental analysis, MALDI-TOF mass spectrometry,H-1, and(31)P NMR spectroscopy. The molecular and crystal structures of3aand3bwere confirmed by single crystal X-Ray crystallography. Hirshfeld surface analyses of the crystal structures of3aand3bwere investigated to determine the remarkable interactions between the molecules and the packing nature of the molecules in the crystals.
