Compounds possessing a thioamide function play a crucial role in organic synthesis,
serving as key building blocks. They are also important in the pharmaceutical chemistry and …

As a readily available and benign waste product of the petrochemical industry, elemental
sulfur displays desirable characteristics as a raw material for new processes. Accordingly …

The oxidative amination of alkynes typically requires transition metal catalysts and strong
oxidants. Herein, we alternatively utilize DABCO as a sulfur-activating catalyst to achieve the …

While elemental sulfur has been largely used as oxidant or sulfurating agent, its role as a
catalyst has not been developed. We report here its catalytic activity in the oxidative …

A mild, greener approach toward thioamide synthesis has been developed. Its unique
features include water-mediated reaction with no input energy, additives, or catalysts as …

An efficient iodine-imine synergistic promoted Povarov-type multicomponent reaction was
reported for the synthesis of a practical 2, 2′-biquinoline scaffold. The tandem annulation …

Photoresponsive spin-crossover (SCO) molecules are an important class of bistable
magnetic molecules with intriguing potential in device applications. The light-induced …

A metal-free oxidative cyclization of trifluoroacetimidohydrazides with methylhetarenes for
the efficient synthesis of 3-hetaryl-5-trifluoromethyl-1, 2, 4-triazoles has been developed …

We have developed a practical, general protocol for denitration of readily available α‐
nitroketones with sulfur and amines to access a broad range of α‐ketothioamides under mild …

Main observation and conclusion: A metal‐free approach for the synthesis of 3‐hetaryl‐5‐
trifluoromethyl‐1, 2, 4‐triazoles via sulfur/dimethyl sulfoxide‐promoted oxidative cyclization …
