The oxidative coupling polymerization of 2,6-dimethylphenol catalyzed by a μ-OCH3-bridged dicopper(II) complex catalyst

Copper‐Mediated Selective Oxidation of a CH Bond

“…A PLATON [19] representation of the molecular structure of this compound is depicted in Figure 1. As previously postulated by several authors, [20] a dinuclear copper(ii) species bridged by both a methoxide and a pentafluorophenoxide is obtained. To the best of our knowledge, this is the first crystallographic evidence of a selfassembled, mixed m-methoxo-m-phenoxo-bridged dinuclear copper complex with a mononucleating nonbridging ligand, namely, neocuproine.…”

Aerobic Copper-Catalyzed Organic Reactions

“…The first reports of the oxidative copper-catalyzed polymerization used pyridine as the amine ligand . A number of additional amine ligands have also been shown to increase the reaction rate, including 1,3-diphenylguanidine, N , N -diphenylformamidine, alkylamines, , bicyclic amidines, N -alkylimidazoles, bridging heterocycles, and 2,2-bipyridines. , Polymeric pyridines, such as polyvinylpyridine (PVP), can also be used, though the effect on reaction rate is dependent on reaction conditions . PVP can be immobilized on silica, which allows for recycling of catalyst at the expense of reactivity .…”

Recent advances in transition-metal-catalyzed selective oxidation of substituted phenols and methoxyarenes with environmentally benign oxidants

“…A c c e p t e d M a n u s c r i p t Edited July 31 13 In the past decade, both mono and dinuclear copper compounds were implicated as active catalysts for the oxidative polymerization of substituted phenols [68][69][70][71]. However, only few systematic studies on the structure-reactivity relationships have been published, and the question about nuclearity of the active copper complex still remains under debate [60,71,72].…”
