微波促进水溶液中羰基化合物α位C-H键的碘代反应

摘要

The iodination of organic molecules such as carbonyl compounds,di carbonyl compounds and heterocycles by elemental i-odine and H2 O2 in water were reported. The iodo-substituted organic compounds were synthesized in 85%-94% yield within 10-20 min under microwaves.%在微波辐射下,羰基化合物的α位C-H键在碘单质和双氧水的共同作用下发生碘代反应。羰基化合物、二羰基化合物和含羰基的杂环类化合物均能很好的反应。该方法反应速度快,10-20 min内收率85%-94%,且有较好的区域选择性。
