Abstract
Non-equivalence of fluorine atoms has been observed in the 19F n.m.r. spectra of 1-alkyl-1,1-difluoro-N-methyl-N′-phenyl-1,2,4-phosphadiazetidin-3-ones at -40°C but not in the spectra of analogous N,N′-dimethyl compounds and a mechanism for pseudorotation in these compounds is proposed to explain this difference.
