Catalysis
A MOF that merges Cu and Ru photocatalysis
Open access · cc by · source: Europe PMC
CR–BPY1 places copper ions next to a Ru-substituted polyoxometalate so N-phenyl-THIQ and ketones couple under an 18 W lamp with pore size-selectivity.
Key findings
Nitromethane coupling gives 90% yield in 24 h and recycles 90→82% over three runs. Filtration stops the reaction (true heterogeneous). A bulky ketone gives <10% conversion because it cannot enter the channels. Homogeneous Cu or POM controls give only 25–42%.
Methodology
Authors built a copper–bipyridine MOF encapsulating [SiW11O39Ru(H2O)]5−, then ran oxidative couplings of N-phenyl-tetrahydroisoquinoline with nitromethane or acetophenone under household fluorescent light.
Limitations
A broad substrate table beyond a few amines/ketones and long-term flow operation are not provided; grinding to 2 μm only modestly speeds the reaction.
