Tanini, Damiano; Dalia, Camilla; Capperucci, Antonella published an article in 2021, the title of the article was The polyhedral nature of selenium-catalyzed reactions: Se(IV) species instead of Se(VI) species make the difference in the on water selenium-mediated oxidation of arylamines.SDS of cas: 38939-88-7 And the article contains the following content:
On water selenium mediated oxidation of anilines was reported. In the presence of di-Ph diselenide or benzeneseleninic acid, anilines reacted with hydrogen peroxide, providing direct and selective access to nitroarenes. On the other hand, the use of selenium dioxide or sodium selenite lead to azoxyarenes. Careful mechanistic anal. and 77Se NMR studies revealed that only Se(IV) species, such as benzeneperoxyseleninic acid, were the active oxidants involved in the catalytic cycle operating in water and leading to nitroarenes. While other selenium-catalyzed oxidations occurring in organic solvents were recently demonstrated to proceed through Se(VI) key intermediates, the on water oxidation of anilines to nitroarenes does not. These findings shed new light on the multifaceted nature of organoselenium-catalyzed transformations and open new directions to exploit selenium-based catalysis. The experimental process involved the reaction of 2-Chloro-4-methyl-1-nitrobenzene(cas: 38939-88-7).SDS of cas: 38939-88-7
