PEROXIDE ROUTE TO PENTAOXYPHOSPHORANES

A variety of pentaoxyphosphoranes have been prepared by allowing trisubstituted phosphites to react with diethyl peroxide. In one case the same pentaoxyphosphorane was prepared by condensation of β-naphthoquinone and triethyl phoshite and by reaction of the phosphite, 3, with diethyl peroxide. The relative rates of formation of the pentaoxyphosphoranes have been obtained as a function of structure. Decomposition of five-membered ring containing pentaoxyphosphoranes gives epoxides in a stereospecific process. © 1969, American Chemical Society. All rights reserved.
