Oxidative coupling information


Oxidative coupling in chemistry is a coupling reaction of two molecular entities through an oxidative process. Usually oxidative couplings are catalysed by a transition metal complex like in classical cross-coupling reactions, although the underlying mechanism is different due to the oxidation process that requires an external (or internal) oxidant.[1][2] Many such couplings utilize dioxygen as the stoichiometric oxidant but proceed by electron transfer.[3]
