The coordination of pyridylcarboxylate (isonicotinic acid, IN) with copper (II) fabricates a Cu(IN)-MOF. The characteristic properties of the Cu(IN)-MOF are obtained via different analysis techniques such as XRD, SEM, BET, ICP, TG, etc. The advantage of copper(II) coordinated with a bi-functional organic linker (IN), containing a pyridyl and carboxylate group, is demonstrated by the chemical properties of which the Cu(II)-based MOF exhibits excellent catalytic performance for the CO2 carboxylation of terminal alkynes. No noble-metal, co-catalyst, or additives are required to execute the reaction. The effectiveness of the Cu(IN)-MOF was demonstrated with a variety of substrates (>11). Moreover, the Cu(IN)-MOF, as a heterogeneous catalyst, can be recycled at least 5 times retaining its excellent catalytic performance. Herein, we report the first copper (II) metal-organic framework (Cu(IN)-MOF) applied for the carboxylation of alkynes with CO2 demonstrating several advantages such as stable catalyst, avoiding the use of an expensive noble-metal, straightforward synthesis.
