, p. 739 - 749 (2021/01/09)
An alternative thioesterification reaction via copper-catalyzed oxidative coupling of readily available aroylhydrazides with disulfides is developed, in which oxidative expulsion of N2 overcomes the activation barrier between the carboxylic acid derivativ
A new method for synthesis of S-aryl-O-alkyl thiolcarbonates: Selenium-catalyzed reaction of alcohols with carbon monoxide and diaryl disulfides

A unique catalytic ability of selenium has been developed. When alcohols were allowed to react with diaryl disulfides in the presence of a catalytic amount of selenium under a pressurized carbon monoxide, S-aryl-O-alkyl thiolcarbonates were obtained in moderate to good yields.

The Kinetics and mechanism of the reactions of O-ethyl S-(Z)aryl thiocarbonates with (X)benzylamines in acetonitrile at 45.0 °C are studied. Relatively small values of βx (βnuc) = 0.6 to approximately 0.8 and βz (βlg) = -0.5 to approximately -0.7 together with a negative cross-interaction constant ρxz (= -0.47) and failure of the reactivity-selectivity principle (RSP) are interpreted to indicate a concerted mechanism. The normal kinetic isotope effects (kH/kD = 1.3 to approximately 1.8) involving deuterated benzylamine nucleophiles suggest a hydrogen-bonded, four-center-type transition state.
