CoFe2O4@SiO2/PrNH2 nanoparticles as highly efficient and magnetically recoverable catalyst for the synthesis of 1,3-thiazolidin-4-ones

摘要

An efficient three-component synthesis of 1,3-thiazolidin-4-ones is described by one-pot condensation of aldehydes, aromatic amine and thioglycolic acid with nano-CoFe2O4@SiO2/PrNH2 as a robust heterogeneous catalyst. The significant advantages of this protocol are the use of magnetically recoverable catalyst, high to excellent product yields, operational simplicity and the use of CoFe2O4@SiO2/PrNH2 nanoparticles as an environment-friendly catalyst.
