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.
