Abstract
The thermal heterolytic scission of two symmetrical disulphides to give the parent thiol and a mesoionic compound containing two fewer hydrogen atoms is shown to follow first-order kinetics in a variety of solvents; there is a linear correlation between log k and the polarity parameters Y and Z.
