Activation of Carbon Dioxide by Tetraphenylporphinatoaluminium Methoxide. Reaction with Epoxide

Abstract

α,β,γ,δ-Tetraphenylporphinatoaluminium methoxide reacts reversibly with carbon dioxide in the presence of 1-methylimidazole, and this carbon dioxide is activated to react with propylene oxide to produce propylene carbonate under atmospheric pressure and at room temperature.
