微波促进下,1,2-二氯乙烷为溶剂、反应温度120℃、反应时间1 min,系列芳基硼酸与五水合硝酸铋反应得到芳香族硝基化合物.相对于传统加热条件,微波促进反应具有:选择性高、时间短、副产物少等优点.此外,研究了自由基引发剂对该反应的影响,推测其可能是经过自由基转化. A series of arylboronic acids reacted with bismuth nitrate pentahydrate to obtain aromatic nitro compounds under the condition of microwave irradiation, 1,2-dichloroethane as solvent, reaction temperature of 120 ℃ and reaction time of 1 min. Compared with traditional heating conditions, The reaction has the advantages of high selectivity, short time, less by-products, etc. In addition, the effect of free radical initiator on the reaction was studied, suggesting that it may be through free radical conversion.
