This paper describes a convenient and high yielding three-step approach for the synthesis of trans-tetraphenylporphyrins possessing two thioethers in the ortho positions, which will facilitate the synthesis of more elaborate and complex porphyrin architectures. Their synthesis is realized by a double nucleophilic aromatic substitution of 2equiv of a thiolate on 2, 6-dichlorobenzaldehyde to generate a bis-thioether substituted benzaldehyde. This ...
