“…[10] A couple of metal-free procedures involve the reaction of the sodium salt of dithiocarbamic acid with diazonium chloride [11] and diaryl diazonium salts in the presence of hypervalent iodine, [12] the reaction of certain organometallic reagents with tetramethyllithium disulfide, [13] coupling of sodium dithiocarbamates with aryl iodides or halobenzene. [14] Other protocols such as onepot three component reactions of amines, carbon disulfide with electrophiles including alkyl halides [15] or aryl halides, [16] aryl diazonium fluoroborates, [17] pentafluorobenzonitriles, [18] or benzene boronic acid [19] were reported. However, these methods suffer from high cost, environmental issues, difficulty in preparing the reagent, high reaction temperatures, or multiple reaction steps, which limit their applications.…”
