Abstract

It is widely accepted that trigonal bipyramidal (TBP) hydroxyphosphoranes (such as'3) or their conjugate bases, phosphoranoxide anions (such as 2), are intermediates in nucleophilic displacements at tetracoordinate phosphorus in cyclic P= O bond containing compounds.'Thermally* and hydrolytically3 stable cyclic hydroxyphosphoranes and phosphoranoxide anions have recently been prepared. Spectroscopic evidence for ...
