Abstract

Abstract: The reaction at-70'of dimethylketene with a wide variety of PXYZ gives a series of new 2: 1 adducts containing pentacovalent phosphorus in a five-membered ring (5). Spectroscopic and chemical evidences for structure 5 are presented. Their preferred configurations from pmr spectra are discussed on the basis of trigonalbipyramidal structures. The relative stabilities of the series of adducts (5) are shown to be in accord with the ex- ...
