Brnsted酸性离子液体(ILS)作为双重催化剂和溶剂，为苯乙酮和苯甲醛的Claisen-Schmidt(CS)缩合合成查尔酮提供了一种潜在的替代传统的均相/多相催化剂和溶剂。离子液体具有良好的催化活性和循环利用能力。ILS的阳离子和阴离子结构都会影响ILS的活性。对最佳反应条件进行了考察。
Brønsted acidic ionic liquids (ILs) as dual catalyst and solvent offer a potential substitute for conventional homogenous/heterogeneous catalysts and solvent for Claisen–Schmidt (CS) condensation between acetophenone and benzaldehyde to produce chalcones. The ILs showed good catalytic activities and recycle capabilities. Both the structure of cation and anion of ILs could affect the activity of ILs. The optimized reaction conditions were investigated.
