描述了钯催化的5，10，15-三芳基卟啉与π-延伸的芳基溴（例如9-溴蒽）的镍络合物的直接β-二芳基化。反应在N，N-二甲基乙酰胺中在碳酸钾、新戊酸和催化量的乙酸钯存在下进行，没有任何额外的配体。本文还讨论了芳基化卟啉的吸收和发射性质以及X射线晶体学分析。
Palladium‐catalyzed direct β‐diarylation of the nickel complexes of 5,10,15‐triarylporphyrins with π‐extended aryl bromides, such as 9‐bromoanthracene, is described. The reaction proceeded inN,N‐dimethylacetamide in the presence of potassium carbonate, pivalic acid, and a catalytic amount of palladium acetate without any additional ligands. The absorption and emission properties as well as X‐ray crystallographic analysis of the arylated porphyrins are also discussed.
