Direct oxidative nucleophilicsubstitution of the 3-hydrogen of BODIPY dyes by pyrrole has been developed under reflux condition under oxygen, from which a series of pyrrolyldipyrrinato BF(2) complexes 1a-h, as extended BODIPYs, have been synthesized. Most of these BODIPYs show strong fluorescence emissions at wavelengths over 600 nm in six solvents of different polarity. Removal of the BF(2) group

5-unsubstituted dipyrromethane to the corresponding meso-unsubstituted dipyrrin (method 2). The first method is limited to the synthesis of symmetrical dipyrrins, while the second method is currently limited to the synthesis of dipyrrins with meso-aryl substituents and it requires the synthesis of the dipyrromethane starting material. Dipyrrins with meso-alkyl substituents can be synthesized from alkyl acid
