英文摘要: A simple base functionalized Supported Ionic Liquid Phase Catalyst using 1-hexyl-3-methyl imidazolium hydroxide ionic liquid supported on silica, ([Hmim]OH/SiO2) was used as an efficient, heterogeneous catalyst for the synthesis of quinazoline-2,4(1H,3H)-diones motif through the carboxylative coupling of CO2 with 2-aminobenzonitriles. The reactions give good to excellent yield under optimized reaction condition. The catalyst, [Hmim]OH/SiO2, was synthesized by physical adsorption phenomenon and was characterized by different techniques such as FT-IR and BET (Brunauer-Emmett-Teller) surface area analysis. The influences of different reaction parameters such as catalyst loading, reaction time, solvent, temperature and pressure on the reaction system were investigated. The developed methodology described a simple one step approach for the synthesis of a wide variety of substituted quinazoline-2,4(1H,3H)-diones with excellent yield of a desired products. Furthermore, the catalytic system was found to be recyclable up to four consecutive cycles with marginal decrease in yield after third recycle. © 2014 Elsevier Ltd. All rights reserved.
