The specific synthesis of a metal-free bisdienophilic phthalocyanine 193, suitable for repetitive Diels-Alder reactions, is reported. This was achieved by condensation of 191,3,3-trichloro-6/7-nitroioindolenine (191) and 4,9-dibutoxy-2,3,5,8-tetrahydro-1,3-diimino-1H-5,8-epoxybenz[f]isoindoline (2). The ability of 3 to undergo Diels-Alder reactions was tested by reaction with an excess of 1,2,3,4-
报道了适用于重复Diels-Alder反应的不含金属的双双亲酞菁193的特定合成。这是通过冷凝实现191,3,3-三氯6/7-nitroioindolenine(191)和4,9-二丁氧基2,3,5,8四氢-1,3-二亚氨基-1- ħ -5, 8-环氧苯并[ f]异吲哚啉(2)。通过与过量的1,2,3,4-四苯基环戊二烯酮(5)反应来测试3进行Diels-Alder反应的能力。半卟啉9、10和11的实验数据实验部分还提供了可用于合成梯形聚合物的前体的化合物。
