Abstract

Abstract Several [sgrave]-dioxyphosphoranes have been prepared and their structural characterizations using NMR techniques support the trigonal bipyramidal conformer as the most stable for the acyclic phosphoranes. Their utility in smooth conversions of hydroxylated substrates [HO (CHR) n XH, n= 2–6; X= O, S, NH] to the corresponding X-heterocycles is documented.
