## Abstract The kinetics and mechanism of the aminolysis of aryl dithiobenzoates (RC(ο£ΎS)SC~6~H~4~Z; R = Ph) with pyridines (XC~5~H~4~N) in acetonitrile at 60.0Β°C have been studied. A biphasic BrΓΆnsted plot is obtained with a change in slope from a large value (Ξ²~X~ β‰… 0.7–0.8) to a small value (Ξ²~X~

The kinetics of reactions between Y-benzenesulfonyl chlorides and X-pyridines in methanol at 35.0 Β°C were investigated. Strong para p-acceptors, X = p-CN and p-COCH 3 , give good linear fits to BrΓΈnsted-type plots with low b X (=0.32-0.45) but show positive deviations from linear Hammett plots (& X
