22. Isocorrole also exhibits a similar kind of tautomerism. For details see: (a) Will, S.; Rahbar, A.; Schmickler, H.; Lex, J.; Vogel, E. Angew. Chem., Int. Ed. Engl. 1990, 29, 1390-1393.

24. The replacement of pyrrole nitrogen by furan oxygen in the tetraphenyl porphyrins results in the blue shift of the absorption bands and the magnitude of the shift depending on the number of oxygens present in the core. For details see: Sridevi, B.; Narayanan, S. J.; Srinivasan, A.; Reddy, M. V.; Chandrashekar, T. K. J. Porphyrins Phthalocyanins 1998, 2, 69-78.

26. In a typical reaction, for example, 1 (386 mg, 1.02 mmol) was reacted with 3 (97 mg, 1.02 mmol) in dichloromethane (200 mL) containing TFA (0.07 mL, 1.02 mmol) under nitrogen atmosphere with stirring for about 90 min. The reaction was monitored with TLC. After the reaction was completed, the mixture was opened to air and chloranil (251 mg, 1.02 mmol) was added and the mixture was heated at reflux for a further period of 90 min. After the usual workup, the purification by column chromatography with alumina (basic, grade III) the first pink band eluted with 2:8 dichloromethane/petroleum ether gave 6, as a purple solid.
