One-Pot Synthesis Of 1,3-Benzo[d]thiazolederivatives Promoted By Al(HSO4)3 Under Solvent Free Conditions
Authors
Abstract:
Heterogeneous reagent systems have many advantages such as simple experimental procedures, mild reaction conditions and minimization of chemical wastes as compared to the liquid phase counterparts. Al(HSO4)3 as an heterogeneous, efficient, readily available, and cheap catalyst was synthesized and applied for the synthesis of 1,3-benzo[d]thiazole derivatives by condensation protocol of 2-aminothiophenol and aldehydes under solvent free conditions. Short reaction times, high yields, a clean process, simple methodology, easy work-up and green conditions are some advantages of this protocol.

The chemistry of 2-oxo-1,2,3,4-tetrahydropyrimidines began to develop toward the end of 1893 year, when the first representatives of this class compounds were reported by P. Biginelli. Despite prior reports of several really effective catalytic and non-catalytic approaches towards Biginelli-type products, an overwhelming number of new catalysts for the Biginelli reaction have been recently publ...

Fe3O4 nanoparticles were employment as an efficient and magnetically separable Nano catalyst for the synthesis of amides via one-pot Beckmann rearrangement of ketones under solvent-free conditions. Various secondary amides were synthesized by this method in moderate to good yields. The catalyst showed high thermal stability and was recovered and reused at least five times without any considerab...
