The inorganic–organic hybrid polyhedral oligomeric silsesquioxane magneticnanoparticles were used as an efficient new heterogeneous catalyst for the one‐pot three‐component synthesis of 1,3‐thiazolidin‐4‐ones under solvent‐free conditions. Moreover, these nanoparticles could be easily separated using an external magnet and then reused several times without significant loss of catalytic activity. Copyright
CoFe<sub>2</sub>O<sub>4</sub>@SiO<sub>2</sub>/PrNH<sub>2</sub> nanoparticles as highly efficient and magnetically recoverable catalyst for the synthesis of 1,3-thiazolidin-4-ones
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.
Visible-light-promoted C N and C S bonds formation: A catalyst and solvent-free photochemical approach for the synthesis of 1,3-thiazolidin-4-ones
A visible-light-induced, one-pot mild and efficient, multicomponent-tandem synthesis of diversified 1,3-thiazolidin-4-ones under catalyst and solvent-free conditions is reported. Here, visible-light, an ideal source of energy, has been used as photochemical activator to generate CN and CS bonds under radical mechanistic pathway from aromatic amines, aldehydes and thioglycolic acid.
