Copper-catalyzedcoupling of thiols with amines was used to synthesize numerous sulfinamides in excellent yields. Sulfenamides or sulfonamides were also formed as reaction byproducts albeit in trace quantities. The procedure is carried out as a one step and was found to be promoted by the addition of water and NH4PF6 under aerobic conditions. Furthermore, the reaction proceeds smoothly when using disulfides

Copper-catalyzed formation of sulfur–nitrogen bonds can be performed by a dehydrocoupling of aryl thiols with amines. Sulfenamides or sulfonamides can be produced by the use of a copper catalyst in air or under oxygen atmosphere. Furthermore, a reaction involving the combination of a palladium catalyst and a copper catalyst selectively afforded sulfinamides.

process using riboflavin derivatives, which allows aerobic oxidative multistep S–S, S–N, and S–O bond formations of thiols and amines, is presented herein. The reaction proceeded under mild metal-free conditions using air (1 atm) as an environmentally friendly oxidant, yielding sulfinamides and sulfonamides.

lowed by 3-chloroperoxybenzoic acid oxidation of the resulting sul- finamides provides primary, secondary, and tertiary alkane-, arene- and heteroarenesulfonamides in high yields. This constitutes a mild and facile experimental protocol that avoids the use of hazardous, unstable, or volatile reagents and does not affect the configurational stability of the amines
