Novel, High-yielding Synthesis of meso-Substituted Porphyrins via the Direct Arylation of Porphine.
NoA new method for the synthesis of meso-substituted porphyrins is described: reaction of 5,10,15,20-tetrabromoporphine magnesium complex with aryl or heteroaryl boronic acids in the presence of Pd(PPh3)4 gave meso-substituted porphyrins in yields up to 70%
