Synthesis of pure iron(II) mesotetraphenylchlorin complexes via a versatile general method of iron insertion into chlorins

► The procedure allows one to obtain a pure compound. ► Overcomes the problem of oxidation of the TPC. ► The Cadmium complex Cd-TPC is easily accessible with the method (acetate/DMF). ► The reduction of Fe(III) to Fe(II) was carried out with zinc amalgam.
