Synthesis of A2B2 type cis-doubly N-confused porphyrins from N-confused dipyrromethanes

A2B2 type of cis-doubly N-confused porphyrins (cis-N2CP) bearing 2,6-dichloro-, 2-nitro-, 3-nitro-, and 4-nitro-phenyl groups and pentafluorophenyl groups at meso-positions were synthesized by the condensation of aryl-substituted N-confused dipyrromethanes and pentafluorobenzaldehyde. The complexation of rare high oxidation states of metals, Cu(III) and Ag(III), was demonstrated.
