Selective functionalization of sp3-hybridized CÀH bonds of hydrocarbons, for example alkylarenes, to value-added products is of crucial importance.[1] With regard to oxidation of alkylarenes, there have been many efforts to find efficient catalysts to date.[1, 2] For example, toluene, the simplest and readily available alkylarene, has been catalytically converted into oxidized products, such as benzyl alcohol, benzaldehyde, and benzoic ...
