Abstract
Rates of the reaction between CuCl2 or ZnCl2 and protoporphyrin IX dimethyl ester have been measured in NN-dimethylformamide (dmf) or in a benzeneâdimethylformamide binary solvent in the presence of the nitroarene acceptors 1,3,5-trinitrobenzene and 2,4,7-trinitrofluoren-9-one. The results show that the acceptorâporphyrin molecular complex cannot react with the metal. A mechanism for the formation of metalloporphyrins is evaluated on the basis of these studies.
