N,N-Sulfonyldiimidazole - Introduction
N,N-dicyclohexylcarbodiimide (DCC) is an organic compound with the chemical formula C13H22N2S. It is a colorless crystal or powdered solid.It is a commonly used activator and coupling reagent in organic synthesis.
N,N-Thionyl bisimidazole is mainly used to adjust the reactivity between reactants and reagents in chemical reactions.In organic synthesis, it is commonly used in the acylation reaction between carboxylic acids and amines.In this reaction, N,N-thionyl bisimidazole reacts with carboxylic acid to generate the thionyl azide (O-acylisourea) intermediate, which then reacts with the amine to form the amide product.
N,N-Thionyl bisimidazole is a highly efficient reaction activator because it can prepare more reactive thionyl azide intermediates by forming imidazole.It can also be used under neutral or weakly alkaline conditions, making it widely used in organic synthesis.
In addition to its application in acylation reactions, N,N-thiodiazole can also be used as an activator for carbonyl compounds to promote the reaction of nucleophiles with carbonyl compounds to form products such as carboxylic acids or esters.It should be noted that N,N-thiodiazole decomposes when exposed to air and moisture, so it should be stored in a dry environment and the container should be quickly closed when used.
