Highly efficient catalase activity of metallocorroles.
The iron(iii) complex of a bipolar and amphiphilic corrole, which binds strongly to proteins and undergoes protein-mediated cellular uptake, catalyzes the decomposition of hydrogen peroxide faster… Expand
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 [Eq. (1); Ar=C6 F5 , 2,6-F2 C6 H3 , 2,6-Cl2 C6 H3 ]. The product… Expand
Albumin-conjugated corrole metal complexes: extremely simple yet very efficient biomimetic oxidation systems.
An extremely simple biomimetic oxidation system, consisting of mixing metal complexes of amphiphilic corroles with serum albumins, utilizes hydrogen peroxide for asymmetric sulfoxidation in up to 74%… Expand

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… Expand
Highly selective chlorosulfonation of tris(pentafluorophenyl)corrole as a synthetic tool for the preparation of amphiphilic corroles and metal complexes of planar chirality.
[reaction: see text]. The chlorosulfonation of tris(pentafluorophenyl)corrole proceeds with an extremely high selectivity as to afford one out of 139 possible isomers in very high yield. The… Expand
Remarkable Effects of Metal, Solvent, and Oxidant on Metalloporphyrin-Catalyzed Enantioselective Epoxidation of Olefins
Three metal complexes of one particular homochiral porphyrin were investigated as catalysts for enantioselective epoxidation of unfunctionalized olefins under various reaction conditions. Much better… Expand
How acidic are corroles and why
The pH-dependent absorption and emission spectra of the water-soluble 2,17-disulphonato-5,10,15-tris(pentafluorophenyl)corrole revealed that its inner-core nitrogen atoms can be both protonated and… Expand
Exploring the photoexcited triplet states of aluminum and tin corroles by time-resolved Q-band EPR
The photoexcited triplet states of three 5,10, 15-tris(pentafluorophenyl)corroles (tpfc), hosting Sn(IV) and Al(III) in their core, namely, Sn(Cl)(tpfc), Al(pyr)2(tpfc) and Al(pyr)2(tpfc-Br8), were… Expand
