C-H carboxylation of terminal alkynes with CO₂ by immobilized Ag nanoparticles

Abstract

The utilization of CO₂ as a C1 source is remarkable for its abundance and cheapness. It is known that Ag nanoparticle exhibits catalytic activity for C-H carboxylation of phenylacetylene with CO₂. In this study, we immobilized the Ag nanoparticles on various supports such as SiO₂, TiO₂, and ZrO₂ and carried out C-H carboxylation with CO₂ using them. They exhibited activity for the reaction. TiO₂-supported Ag nanoparticle exhibited the highest activity among them.
