Preparation of meso-diethyl-2,2′-dipyrromethane in water
Objective To synthesize meso-diethyl-2,2′-dipyrromethane in water with negligible subsequent purification. Background Dipyrromethanes are used as intermediates for the synthesis of porphyrins and other value-added compounds such as fluorescent markers or coordination compounds. The syntheses of such compounds are generally based on the acid-catalyzed condensation of pyrrole with aldehydes or ketones in an organic solvent. Careful … Read more
