Cover Feature: Synthesis of Porphyrinoids, BODIPYs, and (Dipyrrinato)ruthenium(II) Complexes from Prefunctionalized Dipyrromethanes (Eur. J. Org. Chem. 25/2019)

The Cover Feature shows an illustration of the wide range of pyrrole‐based dye molecules accessible via functionalized dipyrromethanes. Employing 5‐(4‐fluoro‐3‐nitrophenyl)dipyrromethane as the precursor, a highly efficient aromatic nucleophilic substitution with various amines is reported, leading to (4‐amino‐3‐nitrophenyl)‐functionalized dipyrromethanes. These dipyrromethanes can be converted into porphyrinoids, BODIPYs, and (dipyrrinato)ruthenium(II) complexes. Now, the 'quest' for using these compounds as possible photosensitizers for photodynamic therapy can begin. More information can be found in the Full Paper by A. Wiehe et al.
