meso-Pyrimidinyl-Substituted A2B- and A3-Corroles

A variety of meso-pyrimidinyl-substituted A(2)B- and A(3)-corroles (A = 4,6-dichloropyrimidin-5-yl) have been synthesized by careful optimization of the macrocyclization conditions. meso-Pyrimidinylcorroles offer the distinct advantage of an unprecedented broad scope of functionalization options. Highly sterically encumbered triarylcorroles were readily prepared via efficient nucleophilic aromatic substitution and Suzuki cross-coupling procedures.
