Highly Efficient Conversion of Propargylic Alcohols and Propargylic Amines with CO 2 Activated by Noble‐Metal‐Free Catalyst Cu 2 O@ZIF‐8

The noble-metal-free catalyst Cu2O@ZIF-8 with a yolk–shell structure was synthesized, and it represents the first noble-metal-free catalyst that can effectively catalyze both propargylic alcohols and propargylic amines with CO2 under mild conditions.
