Copper‐Catalyzed Hydrocarboxylation of Alkynes Using Carbon Dioxide and Hydrosilanes

Abstract

Getting a fix: The copper-catalyzed hydrocarboxylation of alkynes using carbon dioxide in the presence of a hydrosilane, which serves as a reducing agent, has been developed (see scheme). Copper fluorides bearing N-heterocyclic carbene ligands such as IMes and Cl2IPr show high catalytic activities.
