Constructing highly reactive Pd nanoparticles with π bonds in imidazolium-based metal–organic frameworks for chemoselective CO <sub>2</sub> multicomponent transformation
A scalable π-bond-stabilized 10%Pd@Er-MOF catalyst drives 100% selective 4C-TCRs of propargylic amines, aryl iodides, and in situ -activated CO 2 , yielding oxazolidinones with 99% yield and 227 h −1 TOF.
