Catalytic synthesis of organic cyclic carbonate through CO2 fixation and production of β-amino alcohol via ring opening of epoxides under green condition by polystyrene embedded Al(III) catalyst

Development of low cost, eco-friendly heterogeneous catalyst for the production of value added organic compounds has been drawn a considerable attention to the synthetic chemists in recent era. Keeping the above idea in our mind, we have design and synthesized a polymer anchored Al(III) composite from modified Merrifield resin. The composite was characterized properly by FT-IR spectra, SEM, EDAX, elemental analysis, ICP-AES and PXRD studies. The low cost material is very efficient heterogeneous catalyst for the production of fine organic chemicals such as organic cyclic carbonates and 2-amino alcohols under green and mild reaction conditions. Organic cyclic carbonates were synthesized through the insertion of carbon dioxide into epoxides at room temperature under solvent free condition. The developed protocol of catalytic synthesis of cyclic carbonates is sustainable, eco-friendly and cost-effective. Moreover atmospheric carbon dioxide is utilized here. Besides, the catalyst is very much efficient to produce 2-amino alcohol from ring opening of epoxides by nucleophilic attack of amine under solvent free condition and at room temperature. This polymer anchored Al(III) can be recovered and reused easily. The catalyst preserved its catalytic intensity even after use of eight successive catalytic cycles. (C) 2019 Elsevier B.V.
