How is 2-[(E)-2-{4-[(E)-2-(3-Cyanophenyl)vinyl]phenyl}vinyl]benzonitrile (CAS: 79026-03-2) typically synthesized?

This compound is typically synthesized via a multi-step process involving the formation of an intermediate vinyl cyanide followed by coupling with a phenyl vinyl compound. The synthesis involves the use of transition metal catalysts and requires careful control of reaction conditions to achieve high selectivity and yield. The exact method can vary depending on the specific starting materials and desired end product.
