General Description

4-(Trifluoromethyl)benzenesulfonamide is a chemical compound with the molecular formula C7H6F3NO2S. It is categorized under the class of benzenesulfonamides, organic compounds containing a sulfonamide group that is S-linked to a benzene ring. The trifluoromethyl group attached to the benzene ring enhances the compound’s chemical stability and reactivity due to the high electronegativity of fluorine atoms, thus influencing its physical and chemical properties. It is primarily known for its usage in the synthesis of other chemical compounds and may be used in the production of pharmaceuticals and various other industrial products. However, it should be handled with care, as it can be harmful if inhaled, ingested, or comes in contact with the skin or eyes.

Nickel(II)-Catalyzed Addition of Aryl and Heteroaryl Boroxines to the Sulfinylamine Reagent TrNSO: The Catalytic Synthesis of Sulfinamides, Sulfonimidamides, and Primary Sulfonamides

We report a redox-neutral Ni(II)-catalyzed addition of (hetero)aryl boroxines to N-sulfinyltritylamine (TrNSO). The reactions use a catalyst generated from the combination of commercial, air-stable NiCl2·(glyme) and a commercially available bipyridine lig

Sulfonamide Synthesis through Electrochemical Oxidative Coupling of Amines and Thiols

Sulfonamides are key motifs in pharmaceuticals and agrochemicals, spurring the continuous development of novel and efficient synthetic methods to access these functional groups. Herein, we report an environmentally benign electrochemical method which enables the oxidative coupling between thiols and amines, two readily available and inexpensive commodity chemicals. The transformation is completely driven by electricity, does not require any sacrificial reagent or additional catalysts and can be carried out in only 5 min. Hydrogen is formed as a benign byproduct at the counter electrode. Owing to the mild reaction conditions, the reaction displays a broad substrate scope and functional group compatibility.

Sulfonamide compound and synthesis method and application thereof

The invention discloses a synthesis method of a sulfonamide compound represented in a formula (2). According to the method, diazonium salt is used as a reaction raw material, and under the action of an inorganic nitrogen reagent, an inorganic sulfur dioxide reagent, an additive and a phosphine reagent, the diazonium salt is reacted in a solvent at 60-100 DEG C to obtain various sulfonamide compounds. According to the method inorganic salt is used as a nitrogen atom source and a sulfur dioxide source under a metal-free catalytic condition to construct the sulfonamide compound through one step,thereby avoiding the conventional multi-step synthesis of sulfonamide by condensing unstable acid chloride and amine; and the developed sulfonamide synthesis method can be further applied to the synthesis of the arthritis drug celecoxib and the psychotropic drug sulpiride.
