Using odorless thiourea as the S source, benzothiazoles and asymmetric disulfides could be obtained from thioformanilides through the tandem cyclization/nucleophilic addition/hydrolysis/nucleophilic substitution reaction. Furthermore, the obtained asymmetric disulfides could readily transfer to benzothiazoles after nitro-reduction and amide formation reaction. This metal-free and recyclable synthetic methodology offered a time-efficient, less expensive, and environmentally friendly alternative to multifunctional benzothiazoles.

Hypervalent iodine oxidation of the various hydrazides 1a-h using iodobenzene diacetate (IBD) in methanol, ethanol, and water in acetonitrile, leads to facile cleavage of hydrazino moiety with the formation of corresponding methyl, ethyl esters and carboxylic acids, respectively (Scheme 1).
