Abstract:
The metal-templated condensation strategy has been developed for the synthesis of meso-free bipyricorrole complexes. The reactive meso-CH in the monomer complex is further treated with various oxidative coupling reagents such as AgPF6, AgOTf, and FeCl3. Unlike Ag(I) salts, the FeCl3 resulted in a meso-meso-linked corrole homologue dimer. The synthetic methodologies successfully introduce the PdII monomer as well as PdII-PdII dimeric complexes in the corrole chemistry.
