Eco-friendly synthesis of 2-substituted benzothiazoles catalyzed by silica sulfuric acid

2-Substituted benzothiazoles have been synthesized via one-pot reaction from aromatic aldehydes and o -aminothiophenol catalyzed by silica sulfuric acid in absolute methanol at room temperature. The remarkable advantages offered by this method are an environmentally friendly and reusable catalyst, a...

Description
Summary:2-Substituted benzothiazoles have been synthesized via one-pot reaction from aromatic aldehydes and o -aminothiophenol catalyzed by silica sulfuric acid in absolute methanol at room temperature. The remarkable advantages offered by this method are an environmentally friendly and reusable catalyst, a simple procedure, mild conditions, short reaction times, and good to excellent yields of products.
