Bis-Pocket Porphyrins without meso-Substituents: Tetramethyltetra(2,4,6-triisopropylphenyl)porphyrin I and Tetrametyltetraterphenylporphyrin I

Article abstract of DOI:10.1016/0040-4039(95)01326-D

A facile synthesis of meso-unsubstituted but doubly fenced porphyrins is described.The required pyrroles are made by the Barton-Zard method from 2,4,6-triisopropylbenzaldehyde and 2,6-diphenylbenzaldehyde.An X-ray structure confirms the type I pattern.
