Abstract 2,3-Bis(5-tert-butyl-2-methoxyphenyl)buta-1,3-diene was prepared by bromination of (Z)- and (E)-2,3-bis(5-tert-butyl-2-methoxyphenyl)-2-butene followed by treatment with zinc powder in a mixture of CH2Cl2 and acetic acid, which was converted to the corresponding o-terphenyl skeleton by the condensation with dimethyl acetylenedicarboxylate followed by oxidation with 2,3-dichloro-5,6-dicyanobenzoquinone
摘要 2,3-双(5-叔丁基-2-甲氧基苯基)丁-1,3-二烯通过(Z)-和(E)-2,3-双(5-叔丁基- 2-甲氧基苯基)-2-丁烯,然后在 CH2Cl2 和乙酸的混合物中用锌粉处理,通过与乙炔二羧酸二甲酯缩合,然后用 2,3-二氯-5 氧化,将其转化为相应的邻三联苯骨架,6-二氰基苯醌。图形概要
