Review on Conformational Isomerism in P-O and P-N Bond Containing Compounds

Shiv Prakash Mishra, R. P. Singh

Abstract: The phosphorus-oxygen (P-O) and phosphorus-nitrogen (P-N) bond containing compounds such as the poly-(phosphates and phosphazenes) were shown the stereochemistry as conformational isomerism with chair-boat conformation. These compounds having the molecular symmetry (C3v, C2h and D3h) in their novel structure. The stereo structure of these polymeric P-O and P-N bonded compounds have been well characterized by IR, X-ray, Raman spectra and by 31P NMR analyses.
