In this study, an effective and straightforward strategy for the synthesis of amino-functionalized ILs@SBA-15 catalysts was proposed via mechanochemical grafting. The as-prepared catalysts exhibited impressive catalytic activity for the one-pot synthesis of cyclic carbonates from olefins and CO2 under metal-and cocatalyst-free conditions. The catalyst could be easily recovered without significant decrease in catalytic activity after multiple cycles. Additionally, a possible catalytic mechanism of the oxidative carboxylation reaction of olefins was proposed based on the results of the control experiment.
