An electrochemical multicomponent reaction was established under catalyst-, chemical-oxidant-free and mild conditions, which provides an eco-friendly and simple protocol for constructing 4-selanylpyrazoles from easily available raw materials with high yields.

A safe, practical and eco-friendly method for the switchable synthesis of sulfoxides and sulfones through visible-light-initiated oxygenation of sulfides at ambient temperature under transition-metal-, additives-free and minimal solvent conditions. The...

A facile and general method for the synthesis of indole‐1‐carboxamides was developed via copper(I)‐catalyzed N‐carboxamidation of indoles with isocyanates under mild reaction conditions. This process is scalable and tolerates a wide spectrum of indoles and isocyanates to deliver corresponding products in good to excellent yields, providing a viable synthetic approach to indole‐1‐carboxamides, which can be used for the treatment of inflammatory diseases and diabetes.

Developments in transition-metal-free trifluoromethylation have attracted broad interests driven by the increasing importance of CF3-containing compounds. Among diverse trifluoromethylation reagents, Togni’s reagents displayed exceptional reactivities, and abundant meaningful organic transformations...

Rapid and efficient protocol for thioamides via microwave-assisted iodine-catalyzed oxidative coupling of dibenzyl(difurfuryl)disulfides with amines.
