膦类离子液体, 因其好的热稳定性以及在弱碱性介质中的惰性等优异特点, 正在受到越来越多的关注. 以廉价的三丁基膦和各种卤代烃为原料, 制备了一系列季膦离子液体, 然后以其与水组成的复合体系为反应介质, 在催化剂1,4-二氮杂二环[2.2.2]辛烷(DABCO)作用下, 进行了各种醛与丙烯腈、丙烯酸甲酯及丙烯酰胺的Morita-Baylis-Hillman 反应研究. 实验结果表明, 在室温条件下, 溴化乙基三丁基膦与水组成的复合溶剂体系, 有效地促进了各种芳香醛及脂肪醛的Morita-Baylis-Hillman 反应, 不仅反应速度快, 而且目标产物产率高.

Phosphonium ionic liquids, due to their superior thermal stability and an inertness in weak basic reaction media, are receiving more and more attention. A series of phosphonium ionic liquids have been prepared starting from cheap tributylphosphine with various halogenated hydrocarbon. Then using 1,4-diazabicyclo[2.2.2]octane (DABCO) as catalyst and water-phosphonium ionic liquid composite system as reaction media, Morita-Baylis-Hillman reactions of a variety of aldehydes with acrylonitrile, methyl acrylate or acrylamide were studied. Experimental results showed that the composite system of phosphonium ionic liquid with water can effectivily accelerate the Morita-Baylis-Hillman reactions of aromatic aldehydes and aliphatic aldehydes, and fast reaction rate and high yield were obtained.
