Reduction of Nicotinamides, Flavins, and Manganese Porphyrins by Formate, Catalyzed by Membrane-Bound Rhodium Complexes

Dioxygen reduction catalyzed by dicobalt Pacman complexes

The development of fuel cell technologies for automotive use in particular is integral to clean and sustainable energy generation, and relies on catalysts to carry out fundamental chemical redox reactions at the electrodes. At present, the four-electron reduction of dioxygen to water that occurs at the cathode is the most problematic as it is catalysed by expensive Pt metal that requires consid...

Visible light promoted hydration of alkynes catalyzed by rhodium(III) porphyrins.

Visible light promoted hydration of a wide scope of alkynes to ketones catalyzed by rhodium(III) porphyrin complexes was described. The key intermediate β-carbonyl alkyl was observed and independently synthesized. The rate of photolysis is over two orders of magnitude faster than that of the thermal process.

Reduction of Quinones by NADH Catalyzed by Organoiridium Complexes**

Biomimetic oxidation of piperine and piplartine catalyzed by iron(III) and manganese(III) porphyrins.

Synthetic metalloporphyrins, in the presence of monooxygen donors, are known to mimetize various reactions of cytochrome P450 enzymes systems in the oxidation of drugs and natural products. The oxidation of piperine and piplartine by iodosylbenzene using iron(III) and manganese(III) porphyrins yielded mono- and dihydroxylated products, respectively. Piplartine showed to be a more reactive subst...

Aerobic oxidative N-dealkylation of tertiary amines in aqueous solution catalyzed by rhodium porphyrins.

Aerobic oxidative N-dealkylation of a variety of aliphatic tertiary amines and anilines catalyzed by rhodium(III) tetra (p-sulfonatophenyl) porphyrin ((TSPP)Rh(III)) is achieved in aqueous solution using dioxygen as the sole oxidant.
