Abstract
The reaction of 2,6-dichlorobenzaldehyde and pyrrole gives 5,10,15,20-tetra kis (2,5-dichlorophenyl) porphyrin (3a) in the presence of montmorillonite KSF and FeCl3 in 20% yield. Similarly other o-disubstituted tetraarylporphy rins (3b-d) have been synthesized from corresponding aldehydes.
