Abstract Microwave irradiation accelerates the bromination of 1, 4-quinones and coumarins with (i) bromine adsorbed on neutral alumina in “dry media” and (ii) with iodine monobromide in acetic acid as compared to the reactions run at room temperature. Bromination takes place selectively at active quinonoid position in 1,4-quinones and at α, β-double bond in coumarins.
摘要 与室温下进行的反应相比,微波辐射加速了 1, 4-醌和香豆素的溴化,(i) 在“干燥介质”中吸附在中性氧化铝上的溴和 (ii) 在乙酸中的一溴化碘。溴化发生在 1,4-醌类中的活性醌类位置和香豆素中的 α, β-双键处。
