The first procedure is carried out in dioxane/water using benzoylaminomethyl-4-hydroxybenzoate, while the second one employs a suspension of 4-hydroxy­benzoic acid in dioxane. In both procedures, benzamidomethyl triethylammonium chloride is used for the benzamidomethylation reaction.

	M716 Cynthia P. Tidwell, L. Dalila Fondren and David E. Nikles Short Note: Copper 5,10,15,20-Tetra(N-ethyl-3-carbazolyl) Porphyrin Molbank 2011, 2011(1), M716; doi:10.3390/M716 Received: 30 December 2010 / Accepted: 25 January 2011 / Published: 28 January 2011 Show/Hide Abstract | Download PDF Full-text (108 KB) |  Abstract: The copper complex of 5,10,15,20-Tetra(N-ethyl-3-carbazolyl) porphyrin was synthesized and characterized by electronic absorption spectrophotometry and cyclic voltammetry. The spectral data were in agreement with the proposed structure. The copper complex exhibited a shift in the Soret band in comparison to the non-metallated porphyrin and the extinction coefficient for the Soret band was on the order of 105 cm−1M−1. Trends observed in the oxidation and reduction potentials were consistent with the nature of the porphyrin. That is, the electron donating group in 5,10,15,20-tetra(N-ethyl-3-carbazolyl) porphyrin enhances oxidation and inhibits reduction.
