Excellent yields of the carbaporphyrin 1 are obtained by application of the “3 + 1” methodology for the reaction of 1,3‐indenedicarboxaldehyde with a tripyrrane in the presence of 5% CF 3 CO 2 H in CH 2 Cl 2 . The related formylcarbaporphyrin 2 was prepared similarly. In contrast to earlier claims, no unusual tautomers or conformers are observed in solution.
