Copper-catalyzed fixation of carbon dioxide: hydrocarboxylation and silacarboxylation

Abstract

Carbon dioxide (CO₂) is a readily available and renewable chemical feedstock, although thermodynamic considerations limit its widespread use in chemical reactions. For effective utilization of CO₂, transition-metal catalysts are requisite. In the present study, we report copper-catalyzed hydrocarboxylation and silacarboxylation of alkynes using CO₂ (1 atm).
