Significance

A polymer-supported nanogold catalyst was found to promote fixation/incorporation of CO₂ to terminal epoxides to give cyclic carbonates (4 examples, 90-94%, TOF: up to 57900). Carbonylation of primary amines with CO₂ also took place in the presence of the nanogold catalyst to afford disubstituted ureas (2 examples, 83-85%). The catalyst is readily prepared from IRA-400 polymer and HAuCl₄·4H₂O.

Comment

During the last two decades, the chemical fixation/incorporation of CO₂ has received much attention due to the economic and environmental benefits of its utility as a safe and cheap C₁ unit agent.
