The present invention relates to methods for accelerating the trans-cis isomerization of 1,2-diphenylethylene analogues by using photocatalyst. According to this invention, in the presence of polypyridyl platinum(II) complex with catalytic dosage, a solution containing trans-1,2-diphenylethylene analogues or mixture of cis- and trans-1,2-diphenylethylene analogues is irradiated by visible light to prepare product of cis-1,2-diphenylethylene analogues or product predominantly being cis-1,2-diphenylethylene analogues under inert gas atmosphere. This method has the advantages of fast reaction, high performance, easy separation of reaction system and recycle of the polypyridyl platinum (II) complexes.
本发明涉及利用光催化剂加速1,2-二苯乙烯类似物的反式-顺式异构化的方法。根据本发明,在存在具有催化剂剂量的多吡啶基铂(II)配合物的情况下,通过可见光照射含有反-1,2-二苯乙烯类似物或反-和顺-1,2-二苯乙烯类似物混合物的溶液,制备顺-1,2-二苯乙烯类似物产品或在惰性气氛下主要为顺-1,2-二苯乙烯类似物的产品。该方法具有反应快、性能高、反应系统易分离和多吡啶基铂(II)配合物可循环利用的优点。
