Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 72830-09-2, Name is 2-Chloromethyl-3,4-dimethoxypyridinium chloride, molecular formula is , belongs to pyridine-derivatives compound.

Reduction of dioxygen to water by a Co(N2O2) complex with a 2,2 ‘-bipyridine backbone
We report a Co-based complex for the reduction of O-2 to H2O utilizing decamethylferrocene as chemical reductant and acetic acid as a proton donor in methanol solution. Despite structural similarities to previously reported Co(N2O2) complexes capable of catalytic O-2 reduction, this system shows selectivity for the four-electron/four-proton reduction product, H2O, instead of the two-electron/two-proton reduction product, H2O2. Mechanistic studies show that the overall rate law is analogous to previous examples, suggesting that the key selectivity difference arises in part from increased favorability of protonation at the distal O position of the key intermediate Co(III)-hydroperoxide, instead of the proximal one. Interestingly, no product selectivity dependence is observed with respect to the presence of pyridine, which is proposed to bind trans to O-2 during catalysis.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 72830-09-2, in my other articles.
