Zusammenfassung:	Deprotection procedure of benzylic ethers. The invention relates to a process of deprotection or removal of the arylmethyl group (debenzylation) in benzylic ethers in order to release the corresponding alcohols using infinitesimal amounts of a nickel compound and a triazole derivative, and exclusively using molecular oxygen as the oxidizing agent and in an ether or polyol type solvent. (Machine-translation by Google Translate, not legally binding) Procedimiento de desprotección de éteres bencílicos. La invención se refiere a un procedimiento de desprotección o retirada del grupo arilmetilo (desbencilación) en éteres bencílicos para así liberar los correspondientes alcoholes utilizando cantidades infinitesimales de un compuesto de níquel y un derivado de triazol, y empleando exclusivamente oxígeno molecular como agente oxidante y en un disolvente de tipo éter o poliol.
