The structures of 3-6 have been determined mainly by elemental analysis, MS, 31P and 1H NMR spectral data. Furthermore, thermal characteristics of the synthesized compounds 4 and 6 were evaluated using Differential Scanning Calorimetric (DSC) measurements. NMR spectroscopic data, product types and relative yields are compared with those of the previously investigated derivatives of N3P3Cl6 (1) with mono and difunctional reagents.
