palladium‐catalyzed intramolecular oxidative CH/CH cross‐coupling reaction. This reaction provides a variety of π‐conjugated molecules bearing heteroatoms, such as nitrogen, oxygen, phosphorus, and sulfur atoms, and a carbonyl group. The π‐conjugated molecules were synthesized efficiently, even in gram scale, and larger π‐conjugated molecules were also obtained by a double CH/CH cross‐coupling reaction and successive
含杂原子的阶梯型π共轭分子的合成通过钯催化的分子内氧化性下成功地实现了 H / C ħ交叉偶联反应。该反应提供了各种带有杂原子(例如氮,氧,磷和硫原子)和羰基的π共轭分子。π共轭分子有效地合成,即使在克规模,以及较大的π共轭分子也由双C所得 H / C ħ交叉偶联反应和连续氧化cycloaromatization。
