Abstract

The nmr spectra of seven five-membered ring phosphites and three phosphates have been analyzed exactly in terms of chemical shifts and coupling constants. Both the proton and phosphorus spectra were utilized in the analysis. The phosphorus-proton coupling constants are consistent with a twist-envelope conformation for the five-membered ring. Data obtained from the isobutylene phosphites indicate that the twist in the five-! membered ring ...
