The reaction at room temperature of an aldehyde with excess pyrrole in the absence of solvent affords the meso-substituted dipyrromethane. The reaction is catalyzed with trifluoroacetic acid or with BF9,0(Et)2. The dipyrromethaue is purified by crystallixation or by flash chromatography on silica wi
