Tetra(carboxymethylenoxyphenyl)porphines which are soluble in bases are prepared by hydrolysis of the ethyl esters of tetra(carboxymethylenoxyphenyl)porphines.The starting ethyl esters of the tetra(carboxymethylenoxyphenyl)porphines were synthesized by alkylation of tetra(oxyphenyl)porphines with ethylchloroacetate, as well as by condensation of pyrrole with ethyl esters of formylphenoxyacetic acids.
