RT journal article T1 Silver-Exchanged Zeolite Y Catalyzes a Selective Insertion of Carbenes into C-H and O-H Bonds A1 Zheng, Yongkun A1 Vidal Moya, Alejandro A1 Hernández Garrido, Juan Carlos A1 Mon, Marta A1 Leyva-Pérez, Antonio A2 Ciencia de los Materiales e Ingeniería Metalúrgica y Química Inorgánica K1 Carbene compounds K1 Catalysts K1 Cations K1 Chemical reactions K1 Zeolites AB Commercially available zeolite Y modulates the catalytic activity and selectivity of ultrasmall silver species during the Buchner reaction and the carbene addition to methylene and hydroxyl bonds, by simply exchanging the counter cations of the zeolite framework. The zeolite acts as a macroligand to tune the silver catalytic site, enabling the use of this cheap and recyclable solid catalyst for the in situ formation of carbenes from diazoacetate and selective insertion in different C-H (i.e., cyclohexane) and C-O (i.e., water) bonds. The amount of catalyst in the reaction can be as low as ≤0.1 mol % silver. Besides, this reactivity allows deeply drying the HY zeolite framework by making the strongly adsorbed water molecules react with the in situ formed carbenes.
