Lubov N. Sobenina, Alexander M. Vasil'tsov, Olga V. Petrova, Konstantin B. Petrushenko, Igor A. Ushakov, Gilles Clavier, Rachel Méallet-Renault, Albina I. Mikhaleva, Boris A. Trofimov, Org. Lett. 2011, 13, 2524-2527. A general efficient route to hitherto inaccessible symmetric and asymmetric meso-CF3-BODIPY dyes has been developed. The key stages include the reduction of available 2-trifluoroacetylpyrroles to the corresponding alcohols which are further condensed with pyrroles. The method allows the BODIPY with 3(5)aryl(hetaryl) and 3,5-diaryl(hetaryl) substituents to be readily assembled. The BODIPY dyes synthesized fluoresce (Qantum yields = 0.56–1.00) in the 560–680 nm region.
