Functionalized IRMOF-3: an efficient heterogeneous catalyst for the cycloaddition of allyl glycidyl ether and CO2
1Division of Chemical and Biomolecular Engineering, Pusan National University, Busan 609-735, Korea.
Abstract:
Functionalized metal organic framework F-IRMOF-3 having quaternary ammonium group was prepared by a fast precipitation and solvothermal method. They showed good catalytic performance for the cycloaddition of allyl glycidyl ether (AGE) and carbon dioxide without any solvent. F-IRMOF-3 with a larger alkyl chain structure and more nucleophilic anion exhibited better reactivity for the cycloaddition reaction. The introduction of a defective ZnO to F-IRMOF-3 by the fast precipitation method becomes more advantageous than the conventional solvothermal method for the cycloaddition reaction due to acid-base bifunctional active sites. The F-IRMOF-3 can be easily recovered and reused without any considerable loss of initial activity.

The acid-catalyzed addition of water to the double bond of alkenes is a large-scale industrial method used to synthesize low-molecular-weight alcohols. An acidic atmosphere is required to allow the hydrogen in the water molecule to act as an electrophile and attack the double bond in an alkene. The addition of a proton to the double bond creates a carbocation intermediate. The proton preferentially bonds to the less substituted end of the double bond to create a more stable carbocation...
