A highly efficient magnetically separable copper nanocatalyst has been developed for decarboxylative cross-coupling reaction. It is the first successful copper based heterogeneous system for this type of coupling, providing a low-cost, stable, and environmentally friendly solution that can be re-used for seven consecutive runs without significant loss in catalytic performance.
A highly efficient magnetically separable copper nanocatalyst has been developed for decarboxylative cross-coupling reaction for the alkynylation of haloarenes using alkynoic acid as a reaction partner. The chemical nature, morphology, size, and magnetic properties of the prepared nanocatalyst were studied by SEM, TEM, EDS, FT-IR, VSM, and ICP techniques. Remarkably, this catalyst represents the first successful copper based heterogeneous system for this type of coupling that provides a low-cost, stable, and environmentally friendly magnetically recoverable entity that can be re-used for seven consecutive runs without appreciable loss in its catalytic performance.
