DABCO-modified super-paramagnetic nanoparticles as an efficient and water-compatible catalyst for the synthesis of pyrano[3,2-c:5,6-c']dichromene-6,8-dione derivatives under mild reaction conditions

In this paper, a novel catalyst is introduced based on the immobilization of 1,4-diazabicyclo[2.2.2] octane (DABCO) on super-paramagnetic iron oxide nanoparticles. For the synthesis of the catalyst, silica-magnetic iron oxide core-shell nanoparticles were

Reaction of dimethyl sulfoxide-acetic anhydride with 4-hydroxy-coumarin, its derivatives under microwave conditions

4-Hydroxycoumarin and various biscoumarins synthesized under microwave conditions were treated with the DMSO-Ac2O reagent under the same conditions to yield different products. A comparative account of the reactions with conventional procedure, as reporte
