Abstract
Comparisons have been made of some kinetic features of the oxidation in alkaline solution of a series of simple aliphatic and aromatic thiols in the presence of added metal catalysts. With ethanethiol as the reactant, the catalytic activity of a wide variety of metals, added to the solution as simple salts, has been determined. Furthermore, using three typical metal catalysts, the oxidation of a series of thiols has been investigated and an attempt has been made to correlate rates of oxidation with the geometric structure and electron‐directing properties of the organic groups present. The size of such groups has been found to be one of the most important factors controlling the overall rate of oxidation.
