The π-extended porphyrins 11a – c with a λmax = 644, 643 and 639 nm were synthesized by an acid catalysed reaction of the dipyrrolylmethane 10 with different aldehydes followed by oxidation with 2,3-dichloro-5,6-dicyano-1,4-quinone (DDQ). In a second approach, 10 was decarboxylated to yield 12, which was treated with DMF and benzoylchloride to give the diformyl compound 13. Acid catalysed reaction
π扩展的卟啉11a – cλmax = 644、643和639 nm是通过二吡咯烷甲烷10与不同醛的酸催化反应,然后用2,3-二氯-5,6-二氰基-1氧化而合成的,4-醌(DDQ)。在第二种方法中,将10脱羧,得到12,将其用DMF和苯甲酰氯处理,得到二甲酰基化合物13。氧化后的12和13的酸催化反应产生卟啉11a。
