Fusion, Dimerization and Conversion

"An unprecedented formation of a meso-fused β–β′ carbaporphyrin dimer and its monomer with a keto group was described. These analogues were synthesized from carbatriphyrin(3.1.1.) by a metal assisted strategy using PtCl2 salt in a single step without any pre-functionalized precursors. Upon dimerization, the monomeric ligand with a di-anionic core is transformed into a dimeric structure with unique tri-anionic cores".
