The First Direct Synthesis of Corroles from Pyrrole.
The solvent-free, catalyst-free condensation of pyrrole and aldehydes provides an extremely facile synthetic pathway to novel corroles, including an ionic, water-soluble corrole.

The first report regarding SOD activity of metallocorroles, investigated via the combination of the cytochrome C assay, pulse radiolysis, and electrochemistry, is used for identifying the main…
Synthesis, spectroscopy, and structures of new rhodium(I) and rhodium(III) corroles and catalysis thereby
The syntheses and molecular structures of six- and five-coordinated rhodium(III) corroles (by pyridines and a chiral amine, respectively) and the rhodium(I) complex of a chiral corrole are described,…
Porphine and pyrrole-substituted porphyrin from cyclocondensation of tripyrrane with mono-substituted pyrroles
The condensation of non-substituted tripyrrane with mono-substituted pyrroles did not lead to corrole, but to porphine and 5-pyrrolyl-porphyrin. Both compounds were fully characterized by a…
One-step conversions of a simple corrole into chiral and amphiphilic derivatives
Abstract The reactions of phosgene with 5,10,15-tris(pentafluorophenyl)corrole and its gallium(III) complex lead to a novel chiral macrocycle and an amphiphilic corrole, respectively. Both types of…
Development of Singlet Oxygen Luminescence Kinetics during the Photodynamic Inactivation of Green Algae
This study incontrovertibly marks a crucial, inevitable step in the investigation of photodynamic inactivation of biofilms: it shows the feasibility of using the singlet oxygen luminescence kinetics to investigate photodynamic effects on surfaces and thus opens a field for numerous investigations.
Microwave-assisted synthesis of non-substituted tripyrrane, tetrapyrrane and pentapyrrane
Abstract The microwave-assisted one-step condensation of aqueous formaldehyde with pyrrole was successfully applied for the preparation of non-substituted tri-, tetra- and pentapyrranes with…
Solvent-Free Condensation of Pyrrole and Pentafluorobenzaldehyde: A Novel Synthetic Pathway to Corrole and Oligopyrromethenes
The solvent-free condensation of pyrrole and pentafluorobenzaldehyde (and to a lesser extent other electron-poor aldehydes as well) leads to a variety of products, of which three have been isolated…
