| مستخلص: |
Silica supported acids like Si-KHSO4, and Si-HClO4 are explored as reusable nano green catalysts for bromination of aromatic and hetero aromatic compounds using KBr under solvothermal, and solvent-free conditions. Reaction times reduced from (4–6) hours under conventional solvothermal protocols to (9–12) minutes under ultrasonic sonucation for completion. But, solvent-free microwave assisted reactions required only (1–5) minutes exhibiting striking rate accelerations compared to the solvothermal and ultrasonic assisted protocols. All the reaction protocols afforded fairly good yields of brominated products, which are comparable with existing protocols. [ABSTRACT FROM AUTHOR] |
