Abstract

Abstract Kinetics of oxidation of 24 S-Arylmercaptoacetic acids (SAMA) by pyridinium chlorochromate (PCC) have been studied in acidmedium. The product of oxidation is the corresponding thiophenol. The rate data of meta-and para-substituted acids have been correlated well with σ I, σ R o values and the meta-compounds correlate well with F, R values. The reaction constants are negative and of smaller magnitudes. Further, the ortho- ...
