Rational design of highly active noble-metal-free heterometallic catalysts for the green fixation CO2 into valuable chemicals is necessary and promising. Herein, a novel three-dimensional (3D) lanthanide-based copper-iodine cluster metal-organic framework has been harvested. Notably, benefiting from abundant Eu(III) [CuxIy] Lewis-acid sites (x = 4, y 3, 4), this compound reveals efficient catalytic performance (99%) cyclicity in carboxylative cyclization both propargylic alcohols amines with under extremely mild conditions (room temperature 1 bar) 6 or 1.5 h, respectively. Furthermore, simulated flue gas 13% large biological macromolecule substrates also can have good applicability, which may be attributed to synergistic effect between as well nucleophilic cocatalyst. DFT (density functional theory) further revealed activation Cu(I) on C≡C bonds amines, providing theoretical guidance preparation material conversion.

Excessive emissions of industrial waste carbon dioxide (CS2) seriously damage the ecological environment. The green and effective conversion into economically valuable chemicals is an emerging approach. Hence, a novel three-dimensional cerium-organic framework (1) was constructed by 4,4′,4″-nitrilotribenzoic acid Ce(NO3)3·6H2O, which exhibited high thermal solvent stability. A unique square channel, rich Lewis sites, stable make 1 efficient catalyst to promote cycloaddition CS2 with aziridine substrates under mild conditions circulate five times without significant decrease in activity. Mechanism exploration indicated that activation, confinement effect, multicomponent synergistic effect promoted process.
