The reaction of 2-formyl-5,10,15,20-tetraphenylporphyrin with aryl methyl ketones and ammonium acetate, in the presence of La(OTf)(3), affords benzoporphyrins and 2-(2,6-diarylpyridin-4-yl)porphyrins. This methodology was used to prepare, for the first time, a 2-(2,2':6',2''-terpyridin-4'-yl)porphyrin. The structures of two 2-(2,6-diarylpyridin-4-yl)porphyrins were confirmed by single-crystal X-ray diffraction.
2-醛基-5,10,15,20-四苯基卟啉与芳基甲基酮和醋酸铵在 La(OTf)(3)存在下反应，生成苯并卟啉和 2-(2,6-二芳基吡啶-4-基)卟啉。该方法首次用于制备 2-(2,2':6',2''-三联吡啶-4'-基)卟啉。两个 2-(2,6-二芳基吡啶-4-基)卟啉的结构通过单晶 X 射线衍射得到证实。
