Abstract A new and green method for the synthesis of α,β-unsaturated arylsulfones had been achieved through the condensation of aromatic aldehydes, chloroacetonitrile, benzenesulfinic acid sodium salt in the presence of 1-butyl-3-methyl imidazolium hydroxide ([bmim]OH) in EtOH under reflux. The ionic liquid was recovered and recycled for subsequent reactions. The advantages of this protocol were non-toxic
摘要在芳香族醛,氯乙腈,苯亚磺酸钠盐在1-丁基-3-甲基咪唑鎓氢氧化物([bmim] OH)存在下的缩合反应中,获得了一种新的绿色合成α,β-不饱和芳基砜的方法。 )在EtOH中回流。回收离子液体并再循环用于随后的反应。该方案的优点是无毒,易于后处理和高收率。
