Ferromagnetic nanoparticle-supported copper complex: A highly efficient and reusable catalyst for three-component syntheses of 1,4-disubstituted 1,2,3-triazoles and C-S coupling of aryl halides
Additive-free synthesis of aryl amines from aryl halides using a reusable water-soluble porphyrin-cored amine-functionalized dendritic polymer copper complex (PPECH–Amine–Cu) catalyst in aqueous media.
A sulfated cyclopentanone-formaldehyde condensate was found to be an effective and reusable catalyst for the dehydration of fructose to 5-hydroxymethylfurfural (HMF).
