Benziporphyrins, porphyrins in which one of the pyrrole units has been replaced by a benzene ring, have proven to be an exitin

Benziporphyrins, porphyrins in which one of the pyrrole units has been replaced by a benzene ring, have proven to be an exciting class of carbaporphyrinoids due to their interesting chemical and spectroscopic properties.  In this study, 9,13,14,18-tetraethyl-3,8,19-trimethyl-22-hydroxybenziporphyrin (1), a porphyrinoid system with an internal hydroxyl substituent, has been synthesized using the ‘3+1’ methodology.   Metalation studies on this novel ligand system are underway.
