| Abstract: | A new, simple and straight-forward protocol for direct carboxylation of terminal alkynes has been developed using
CuII-montmorillonite K10 clay as a
heterogeneous catalyst and CO2 as the C1 carbon feedstock. Also
coupling of terminal alkynes with CO2 (1 atm) in the presence of
alkyl halides has been achieved under the same reaction conditions, thereby
providing access to a variety of functionalized alkyl-2-alkynoates in high
yields.
