Method for synthesizing dicyano diarylethene compound

The invention discloses a method for synthesizing a dicyano diarylethene compound. The method includes: in an air atmosphere, taking substituted phenylacetonitrile as a raw material, taking Ru/C and K2CO3 as catalysts, in o-dichlorobenzene, after the reaction is completed at 140-160 DEG C, separating and purifying the reaction solution, and obtaining the dicyano diarylethene compound. The Ru/C catalyst used in the method not only is inexpensive and easily available, but also is a heterogeneous catalytic system in the reaction. Therefore, the catalyst and a solvent are very convenient to recycle, and can be repeatedly applied. The reaction materials are various and cheap and suitable for synthesizing various substituted dicyano diarylethene compounds. The post-treatment is simple, the product purity is good, and the yield is good. 本发明公开了种二氰基二芳基乙烯类化合物的合成方法，所述方法在空气氛围中，以取代苯乙腈为原料，以Ru/C、KCO为催化剂，在邻二氯苯中，于140～160℃反应完全后，将反应液分离纯化，获得二氰基二芳基乙烯类化合物；本发明所用Ru/C催化剂不仅廉价易得，而且因其在反应中为非均相催化体系，因此其催化剂和溶剂非常方便回收，并且可重复套用；反应原料多样且廉价易得，适合于合
