Activation of C-H bonds of hydrocarbons is one of the thrust areas of research over the years. Designing a robust catalyst, which can work efficiently under eco-friendly conditions for this reaction still remains a big challenge today. Highly dispersed aggregation-free silver nanoparticles (AgNPs) are immobilized over 2D hexagonally ordered functionalized mesoporous silica material via surface thioether functionalization, and the resulting supported AgNPs (AgMS) displayed environmentally benign selective oxidation of C-H bonds of the aliphatic and monocyclic hydrocarbons into their resp. carbonyl compounds The AgMS catalyst exhibited excellent activity toward liquid phase oxidation of C-H bonds under solvent-free and base-free neat conditions using mol. oxygen as the oxidant. This methodol. was successfully applied for the oxidation of substituted toluene, benzylic C-H bonds, and cycloalkanes with very good conversion and selectivity. Moreover, the hydrocarbon conversion and selectivity for the carbonyl products in this partial oxidation reaction have been retained after six reaction cycles. Therefore, immobilization of AgNPs at the surface of ordered mesoporous silica offers a very efficient route in designing a readily separable, reusable, very robust, and promising catalyst for C-H bond activation under eco-friendly reaction conditions.
