Demetalation of the regioselective oxygenation product of an N-confused porphyrin complex.
[structure: see text] The demetalation of M(III)(HCTPPO)Br (M = Mn or Fe) afforded two hydroxylated N-confused porphyrinoids. CTPPOH retains the tautomer form of the N-confused porphyrin with a hydroxyl group substituted in the inner-core carbon. The further attack of OH(-) to the meso carbon afforded a dihydroxylated N-confused macrocycle, CTPP(OH)(2).
