WebMar 23, 2024 · Attack of Boc 2 O on radical intermediate D prior to radical rebound cannot be fully excluded on the basis of the available experimental data. However, in view of the very low computed barrier for the radical rebound step (<2 kcal mol −1), this pathway seems unlikely. Additional catalytic experiments based on the mechanistic insights gathered In this article, we investigated the hydroxylation of methane catalyzed by the binuclear copper site of a pMMO enzyme, through a radical rebound mechanism. All intermediates and transition states along the reaction coordinate were located and the energies involved in the mechanism calculated using the … See more Methanotrophic bacteria are organisms that are capable of selectively activating alkane molecules under mild conditions using Methane Monooxygenase (MMO) enzymes.7The … See more The geometry optimizations were carried out using the hybrid GGA B3LYP functional64,65 including the D2 dispersion correction proposed by Grimme and coworkers.66 … See more In summary, our mechanistic proposal is that one possible mechanism for the oxidation of methane by the binuclear copper site of pMMO proceeds through three fundamental steps: (1) activation of molecular oxygen by … See more WebThese various flavors of the rebound process, often in competition with each other, give rise to the wide range of C–H functionalization reactions performed by iron-containing oxygenases. In this review, we first recount the history of radical rebound mechanisms, their general features, and key intermediates involved. intools inc
