Cycloaddition of Propargylic Amines and CO2 by Ni@Pd Nanoclusters Confined Within Metal-Organic Framework Cavities in Aqueous Solution

The bio-metal-organic framework (bio-MOF) notion along with nanoparticles catalysts of Ni@Pd core-shell magnetic for carbon dioxide conversion is made by l-glutamic acid that is the natural substitute for combinatorial ligands, and illustrated their catalytic effect, in the propargylic amines cyclization with carbon dioxide for obtaining 2-oxazolidinones, completed to the correlation of structure-DFT. This nano Ni@Pd that consists of catalyst is detected using ICP, XRD, TGA, TEM, FT-IR, and VSM. The zinc-glutamate-MOF or ZnGlu is properly proved as the MOF catalyst in the case of the propargylic amines cyclization with carbon dioxide for obtaining 2-oxazolidinones, in addition, its performance is compared to those of outstanding synthetic MOFs stated in the method. The produced catalyst done even at moist state, is thermally as well as chemically firm; easily separable, heterogeneous, because of high selectivity of it, lack of mixture solvents, and also simple catalyst recovery using outside magnet. It is recycled until ten times. Ni@Pd/ZnGlu MNPs dramatically improves the availability of the nanoparticle levels in comparison whit the common substrate because of its 3D hierarchical construction. Ni@Pd/ZnGlu MNPs, because of their economic environmental and economic parameters, are considered as the future of MOF chemistry in industry.
