Abstract Kinetic data on the formation, hydrolysis and thermoly- sis of acyclic phosphoranes is reported and the mechanism of each reaction is discussed. ... INTRODUCTION The reaction of trico-ordinate phosphorus compounds (1) with sul- phenate esters (2) is now a well-established route to a wide range of phosphoranes (3 and 4)l. quantitative data to support the proposed mechanism of biphilic There is however, relatively little ...
