Asymmetric meso-CF3-dipyrromethanes with amino- and nitrogen heterocyclic functions, a new family of the BODIPY dye precursors, have been synthesized in 70-90 % yield by condensation of trifluoro(pyrrolyl)ethanols with pyrroles in the presence of AlCl3. This catalyst, for the first time, was shown to be more efficient than commonly used P2O5, which was entirely inactive in the condensation of pyrroles having basic substituents (amino group and pyrazole moiety).
