Synthesis, characterization, and electrochemical studies of [beta],[beta]'-fused metallocenoporphyrins

The synthesis, characterization, and electrochemical studies of [beta],[beta]'-fused metallocenoporphyrins are described. The novel Pd(0) catalyzed [3@] cycloaddition reaction with porphyrins was studied, a series of [beta][beta]' fused monoruthenoceno metalloporphyrins and bismetalloporphyrins with different central metals were prepared and significant electronic interactions between the metallocene and metalloporphyrin were observed.
