Thioamides can be generated at 100 degrees C in high yield through the reaction of 1,2-dibenzyldisulfane with difurfuryldisulfide using iodine as oxidant and DMSO as solvent. The protocol is metal- and additive-free, providing a convenient and economical way for the synthesis of various kinds of thioamides under mild conditions.

efficient protocol for synthesis of thioamides was developed via the microwave-assisted iodine-catalyzed oxidative coupling of dibenzyl(difurfuryl)disulfides with amines. This process is scalable and tolerates a wide spectrum of amines to deliver the corresponding products in moderate to excellent yields in 10 minutes, providing a cheap and rapid approach to thioamides.
