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.
(Alkylthio)- and (phenylthio)methoxycarbenes from oxadiazolines

Four 2-methoxy-5,5-dimethyl-Δ3-1,3,4-oxadiazolines bearing an alkylthio or arylthio group at C2 were prepared. The oxadiazolines undergo thermolysis at 60-80 °C in solution to afford the corresponding oxythiocarbene intermediates. In the absence of carbene traps, dimers of the carbenes were formed. The carbenes were trapped with ethyl crotonate, with dichloromaleic anhydride, with dimethyl acetylenedicarboxylate, and with phenyl isocyanate. Phenyl isocyanate traps methoxy(methylthio)carbene to form two types of adducts, both fundamentally different from the product obtained from reaction of dimethoxycarbene with phenyl isocyanate. All of the adducts have structures consistent with nucleophilic behaviour of the carbenes.
