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).

The regioselective hydroxyalkylation of 4,5,6,7-tetrahydroindole at position 2 using highly electrophilic polyfluorocarbonyl compounds was performed for the first time. Oxidation of the products thus formed leads to indoles having 2-hydroxypolyfluoroalkyl and polyfluoroacyl groups.

Haloform cleavage of 2-trifluoroacetyl- and N-vinyl-2-trifluoroacetylpyrroles gives pyrrole-2-carboxylic acids and their N-vinyl derivatives in good yields; most of these compounds do not melt between 120-190 deg C, but rather decompose with CO2 evolution.
