How is 4,4'-[(2-Methoxy-1,4-phenylene)di(E)-2,1-ethenediyl]diphenol (CAS: 863918-78-9) typically synthesized?

4,4'-[(2-Methoxy-1,4-phenylene)di(E)-2,1-ethenediyl]diphenol can be synthesized through a multistep process involving the coupling of 4-bromophenol and 4-bromo-2-methoxyphenol followed by the formation of a diene intermediate. The reaction is typically catalyzed by palladium-based catalysts, and the overall yield is around 80-85%. The process requires careful control of reaction conditions to ensure high selectivity and yield.
