Usage

General Description

Cobalt tetrakis(pentafluorophenyl)porphyrin is a chemical compound with the formula Co(TPPF4) and is a member of the porphyrin family. It consists of a cobalt ion at its center surrounded by four pentafluorophenyl groups. Cobalt tetrakis(pentafluorophenyl)porphyrin is mainly used as a catalyst in various organic reactions such as oxidation, reduction, and cyclization reactions. It is also used as a photosensitizer in photodynamic therapy, a treatment for cancer that uses light-activated compounds to kill cancerous cells. Additionally, cobalt tetrakis(pentafluorophenyl)porphyrin has been studied for its potential use in dye-sensitized solar cells and as a model system in bioinorganic chemistry research.

Reaction of a {Co(NO)}8 complex with superoxide: Formation of a six coordinated [CoII(NO)(O2[rad]–)] species followed by peroxynitrite intermediate

A nitrosyl complex of cobalt(II) porphyrinate, [Co(F20TPP2?)(NO)], (F20TPPH2 = 5,10,15,20-tetrakis(pentafluorophenyl)porphyrin) having {Co(NO)}8 configuration was synthesized and characterized by means of spectroscopic and structural analyses. Single crystal X-ray structure of the complex revealed the square pyramidal geometry around the cobalt center with a bent nitrosyl group. It reacts with superoxide (O2[rad]–) ion in CH2Cl2 at ?40 °C to result in the corresponding nitrite (NO2?) complex. Involvement of a cobalt(II)-peroxynitrite intermediate is proposed in the course of the reaction. Moreover, spectroscopic studies suggested the formation of a transient six-coordinated [CoII(NO)(O2[rad]–)] species.

Significantly boosted oxygen electrocatalysis with cooperation between cobalt and iron porphyrins

Developing electrocatalysts for the oxygen reduction reaction (ORR) and the oxygen evolution reaction (OER) is of great importance. Herein, Co tetrakis(pentafluorophenyl)porphyrin (Co-P) and Fe chloride tetrakis(pentafluorophenyl)porphyrin (Fe-P) were loaded on carbon nanotubes (CNTs) for combining the electrocatalytic advantages of both Co-P and Fe-P. The resultant (Co-P)0.5(Fe-P)0.5@CNT composite displayed significantly boosted activity for the selective four-electron ORR with a half-wave potential of 0.80 Vversusreversible hydrogen electrode (RHE) and for the OER with a potential of 1.65 VversusRHE to obtain 10 mA cm?2current density in 0.1 M KOH. A Zn-air battery assembled from (Co-P)0.5(Fe-P)0.5@CNT exhibited a small charge-discharge voltage gap of 0.74 V at 2 mA cm?2, a high power density of 174.5 mW cm?2and a good rechargeable stability (>120 cycles).

Co-Catalyzed Transannulation of Pyridotriazoles with Isothiocyanates and Xanthate Esters

An efficient radical transannulation reaction of pyridotriazoles with isothiocyanates and xanthate esters was developed. This method features conversion of pyridotriazoles into two N-fused heterocyclic aromatic systems-imino-thiazolopyridines and oxo-thia
