Paragraph 0043-0047, (2021/01/30)
The invention discloses a novel, green and efficient method for synthesizing tetraphenolic ethane, and belongs to the field of organic chemistry. The structural formula of the tetraphenolic ethane isshown as 1. The synthesis method of the tetraphenolic ethane comprises the following four steps: synthesis of a photocatalyst CCN-K, synthesis of 4, 4'-(1, 2-bis (4-(benzyloxy) phenyl) ethane 1, 2-diyl) bis (2, 6-di-tert-butylphenol), synthesis of 4, 4'-(1, 2, bis (4-hydroxy phenyl) ethane-1, 2-diyl) bis (2, 6-di-tert-butylphenol) and synthesis of tetraphenolic ethane. The method has the technicaleffects that firstly, the synthetic product tetraphenol ethane plays an important role in the fields of printed circuit boards, electronic and electrical materials, packaging materials, adhesives andthe like; secondly, visible light catalytic synthesis is inserted into the method, so that the method is an efficient and safe environment-friendly technology; and finally, the cost is low, and large-scale preparation can be realized.
