This greener protocol is catalyzed by 1,3‐Dibromo 5,5‐dimethylhydantoin (DBH), and proceeds efficiently in the absence of any organic solvent under thermal condition and microwave irradiation in high yields.enMicrowave irradiationCatalysisCondensationOrganic solventSolventMicrowaveIrradiationArylChemistryCondensation reactionarticle
