Visible-light-assisted aerobic photocatalytic oxidation of amines to imines over NH2-MIL-125 (Ti)
Abstract NH 2-MIL-125 (Ti), an amine-functionalized metal-organic-framework (MOF), was
found for the first time to exhibit photocatalytic activity for the aerobic selective oxidation of
amines to imines under visible light irradiations. Different amines can be effectively
transformed to imines using O 2 over NH 2-MIL-125 (Ti) under visible light irradiations. The
photo-generated Ti 3+ and. O 2− which was formed via the reaction between Ti 3+ and O 2,
are proposed to be involved in this transformation process based on the experimental …

Abstract
NH2-MIL-125(Ti), an amine-functionalized metal-organic-framework (MOF), was found for the first time to exhibit photocatalytic activity for the aerobic selective oxidation of amines to imines under visible light irradiations. Different amines can be effectively transformed to imines using O2 over NH2-MIL-125(Ti) under visible light irradiations. The photo-generated Ti3+ and .O2− which was formed via the reaction between Ti3+ and O2, are proposed to be involved in this transformation process based on the experimental observations and the ESR result. This work provides an economical, sustainable and green process for amines transformations and highlights the great potential of MOFs as photocatalysts for organic syntheses.
