A NEW SYSTEM EXHIBITING A HIGH BARRIER TO ROTATION ABOUT THE P-N BOND. SYNTHESES AND SPECTRAL STUDIES OF 1,3,2-DIAZAPHOSPHETIDIN-4-ONE DERIVATIVES
1,3,2-Diazaphosphetidin-4-one derivatives were synthesized.Their 1H NMR signals at ambient temperature displayed a broad doublet which eventually coalesced before becoming sharp upon warming, and the 13C NMR spectra also showed that the α- and β-carbons o
