Angewandte Chemie International Edition  by Li Ma, Qian Wang, Wai-Lun Man, Hoi-Ki Kwong, Chi-Chiu Ko, Tai-Chu Lau  /   1d   //   keep unread   //   hide   //   preview Abstract The study of manganese complexes as water-oxidation catalysts (WOCs) is of great interest because they can serve as models for the oxygen-evolving complex of photosystem II. In most of the reported Mn-based WOCs, manganese exists in the oxidation states III or IV, and the catalysts generally give low turnovers, especially with one-electron oxidants such as Ce IV . Now, a different class of Mn-based catalysts, namely manganese(V)–nitrido complexes, were explored. The complex [Mn V (N)(CN) 4 ] 2−  turned out to be an active homogeneous WOC using (NH 4 ) 2 [Ce(NO 3 ) 6 ] as the terminal oxidant, with a turnover number of higher than 180 and a maximum turnover frequency of 6 min −1 . The study suggests that active WOCs may be constructed based on the Mn V (N) platform. High turnover : The study of man

The peroxo complexes further react with hydrogen peroxide to give the corresponding nickel(II) hydroperoxides.

Photoinduced electron transfer from substrates to metal complexes with dioxygen also leads to generation of high-valent metal-oxo complexes that can oxygenate substrates. In such a case metal complexes act as a photocatalyst to oxygenate substrates with dioxygen. High-valent metal-oxo complexes are also produced by proton-coupled electron-transf
