Phosphorus ylids find great utility in synthesis where the best known reactions such as the Wittig and variants thereof are used for the construction of carbon-carbon bonds.' We now report a new, sinple reaction of ~tho~carbonylalkylidenephosphoranes with singlet oxygen to
## Abstract Using ^13^Cβchemical shifts as a probe for the electronic environment of carbon centers, triphenylphosphoniomethanide, the model case of a βreactiveβ phosphorus ylid, was found to have much more zwitterion than PC double bond character (resonance structure __1a__ being dominant). Triphe
