The present invention is characterized by subjecting 4,4'-diallyloxydiphenyl sulfone to a rearrangement reaction under microwave irradiation, preferably in molten state, to produce objective 3,3'-diallyl-4,4'-dihydroxydiphenyl sulfone efficiently in a short time, in high yield and in high purity. Further preferably, by carrying out said reaction in substantially oxygen-free atmosphere in the presence of at least one compound selected from a group consisting of an antioxidant, an organic basic compound and a chelate compound, the above-described object can be attained in more preferable manner.
本发明的特点是在微波辐照下,优选在熔融状态下,使 4,4'-二烯丙基氧基二苯砜进行重排反应,以短时间、高产率和高纯度有效地生产客观的 3,3'-二烯丙基-4,4'-二羟基二苯砜。更优选的是,在至少一种选自抗氧化剂、有机碱性化合物和螯合物的化合物的存在下,在基本无氧的环境中进行上述反应,可以更理想地达到上述目的。
