ChemInform Abstract: Polystyrene Resin-Supported CuI-Cryptand 22 Complex: A Highly Efficient and Reusable Catalyst for Three-Component Synthesis of 1,4-Disubstituted 1,2,3-Triazoles under Aerobic Conditions in Water.
A sulfated cyclopentanone-formaldehyde condensate was found to be an effective and reusable catalyst for the dehydration of fructose to 5-hydroxymethylfurfural (HMF).
