Visible-light-assisted aerobic photocatalytic oxidation of amines to Imines over NH2-mIL-125(Ti)

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 transformation and highlights the great potential of MOFs as photocatalysts for organic syntheses.
