Abstract (EN): The present research investigation brings out a novel and relevant catalytic application for the family of MIL-101 metal-organic framework (MOF) materials. The porous Fe(III) terephthalate MOF, MIL-101(Fe) and the corresponding amino-functionalized material, NH2-MIL-101(Fe) showed to be highly active and 100% selective heterogeneous catalysts in the ring opening of cyclohexene oxide in the presence of aniline. The activity of both MOF materials was similar, mainly after 24 h, achieving yields of 87% for trans-2-(phenylamino)-cyclohexanol. The stability and robustness of these MOF materials were confirmed and their capacity to be recycled was also demonstrated. Furthermore, cyclic voltammetry studies revealed that the amine-functionalization of the MIL-101(Fe) results in a significant improvement of the electrochemical response over the unfunctionalized compound, constituting an exceptional advantage of the NH2-MIL-101(Fe) as a future potential electrocatalyst.
