A simple and rapid microwave-assisted synthesis of heteroaromatic appended porphyrins using the Pd/Cu-catalyzed C–C coupling of meso-bromoporphyrins with various five- and six-memberedheteroaromatic azoles has been successfully developed. The prepared heteroaromatic porphyrins 7a-lNi were found to exhibit slightly red-shifted (∼5–10 nm) Soret and Q bands. The developed reaction conditions are useful
已成功开发了一种介孔溴卟啉与各种五元和六元杂芳族吡咯的Pd / Cu催化C-C偶合的简单快速的微波辅助合成杂芳族附加卟啉的方法。发现制备的杂芳族卟啉7a-1Ni表现出轻微的红移(〜5-10 nm)Soret和Q谱带。所开发的反应条件可用于制备不同取代的杂芳族卟啉(A 3 B型和A 2 B 2型)。

In this paper, we developed a technique for the nickel-catalyzed coupling of meso-brominated Ni(II) porphyrins with silylzinc reagents in order to prepare meso-silyl-substituted Ni(II) porphyrins. Porphyrin silylation occurs under mild conditions and exhibits both excellent substrate generality and functional group compatibility.

The synthesis of three possible diporphyrinylamines is described. All compounds were obtained by using the Buchwald-Hartwig aromatic amination reaction. The electronic spectra of the three porphyrin dimers showed characteristic features found In highly delocalized systems. The first oxidation of these compounds took place on the connecting amine function.
