A fast solvent-free method for the metallation of porphyrins is presented. ZnTPP, NiTPP, CuTPP and FeTPP have been prepared mechanochemically by ball milling hydrated metal acetate salts with meso-tetraphenylporphyrin (H2TPP) in a shaker mill for as little as 20 min with no added solvent, avoiding the need for undesirable solvents and long reaction times normally used in such reactions.
