通过Hantzsch二氢吡啶合成，随后在活性炭存在下与分子氧氧化芳构化，和脱羧，合成了线性延伸的联吡啶。通过Suzuki-Miyaura交叉偶联反应合成了4，4“-对三联苯二甲醛。
Linear-extended bipyridines were synthesized via the Hantzsch dihydropyridine synthesis, Subsequent oxidative aromatization with molecular oxygen in the presence of activated carbon, and decarboxylation. 4,4 ''-p-Terphenyldicarboxaldehyde was prepared by the Suzuki-Miyaura cross-coupling reaction.
