The kinetics and mechanism of the reactions of O-ethyl S-(Z)aryl thiocarbonates with (X)benzylamines in acetonitrile at 45.0ЊC are studied. Relatively small values of  X ( nuc ) ϭ 0.6 ϳ 0.8 and  Z ( lg ) ϭ Ϫ0.5 ϳ Ϫ0.7 together with a negative cross-interaction constant XZ (ϭ Ϫ0.47) and failure o
## Abstract The kinetics and mechanism of the aminolysis of aryl dithiobenzoates (RC(S)SC~6~H~4~Z; R = Ph) with pyridines (XC~5~H~4~N) in acetonitrile at 60.0°C have been studied. A biphasic Brönsted plot is obtained with a change in slope from a large value (β~X~ ≅ 0.7–0.8) to a small value (β~X~
