Textbook Question
Chapter 19, Problem 43P
Organic chemists work with tetraphenylporphyrins rather than with porphyrins because tetraphenylporphyrins are much more resistant to air oxidation, Tetraphenylporphyrin can be prepared by the reaction of benzaldehyde with pyrrole. Please a mechanis, for the formation of the ring system shown here:
