Amino-functionalized zirconium and cerium MOFs: Catalysts for visible light induced aerobic oxidation of benzylic alcohols and microwaves assisted N-Alkylation of amines

Herein we report that mixed zirconium-cerium-MOFs with amino-functionalized linkers (2-amino-1,4-benzenedicarboxylate, BDC-NH2, and 4-aminonaphthalene-2,6-dicarboxylate, NDC-NH2) act as effective non-noble-metal-based heterogeneous catalysts, for both the aerobic photooxidation of benzylic alcohols direct microwaves activation N-alkylation amines alcohols. The catalytic performance has been studied considering two different approaches: effect NH2 functionalized hosting CeIII species on Zr-MOFs. Zr- ZrCe-MOFs resulted efficient visible-light-driven photocatalysts high stability considerable recyclability in photocatalytic selective oxidation to aldehydes using molecular oxygen oxidant. These materials are also catalysts microwaves-assisted yielding selectively imine (ZrCe-MOF) or corresponding secondary amine (Ce-MOFs).
