The palladium‐catalyzed coupling of a substituted o‐diaminoanthracene and a substituted o‐diaminophenazine to substituted 2,3‐dichloroquinoxalines furnishes 10 differently substituted N,N′‐dihydrotetraaza‐ or ‐hexaazahexacenes with the quinoxaline group of the azaacenes carrying fluorine, chlorine, or nitro groups. The N,N′‐dihydrotetraazahexacenes with hydrogen, chlorine, and fluorine subtituents are
取代的邻二氨基蒽和取代的邻二氨基吩嗪在钯催化下与取代的2,3-二氯喹喔啉之间的偶合提供了10个不同取代的N,N'-二氢四氮杂或六氮杂六环烯,以及带有氟,氯,或硝基。的Ñ,Ñ '与氢,氯,和氟subtituents -dihydrotetraazahexacenes被氧化成azaacenes,而只有父Ñ,Ñ '-dihydrohexaazahexacenes,具有氢取代基,是由氧化的MnO 2。所得的氮杂并苯乙炔以其光学和光谱数据表征。此外,母体四氮杂六烯及其二氟取代衍生物也获得了单晶X射线结构。N,N'-二氢六氮杂十六碳烯的二氯和四氯衍生物也已进行了结构表征。
