What is Benzothiazole-2-acetonitrile?
The Uses of Benzothiazole-2-acetonitrile
2-Benzothiazoleacetonitrile is used in Organic Synthesis, Pharmaceuticals, Agrochemicals and Dye stuffs.
The Uses of Benzothiazole-2-acetonitrile
2-Benzothiazoleacetonitrile may be used for the preparation of 3-aryl-1-[(E)-cyanomethylidene]-1H-pyrido[2,1-b]benzothiazole-4-carbonitriles, via reaction with with 6-aryl-4-methylsulfanyl-2-oxo-2H-pyran-3-carbonitrile. It may be employed in the preparation of pyrrolones, which can be used for the synthesis of 1-acyl-3-aryl-3H-pyrrolo[2′,3′:4,5]pyrimido[6,1-b]benzothiazol-6-ium-2-olates.
Production Methods
Benzothiazole-2-acetonitrile is produced by the reaction of 1- amino-2-mercaptobenzene (o-aminothiophenol) with the monoiminoether hydrochloride of malononitrile and is used as a condensation component for methine dyes.
