A series of dimethoxybenziporphyrins have been prepared in three steps from 1,3-dimethoxybenzene or 2-methyl-1,3-dimethoxybenzene. Although the free bases are not aromatic, upon protonation there is evidence of a macrocyclic ring current and an increase in aromatic character. Reaction with nickel(II) acetate in CHCl3/CH3OH affords the corresponding organometallic derivatives. Further studies are in progress to exploit this direct route to these carbaporphyrinoids |
