双水相体系中Proline/Cul催化Heck反应的研究
Proline/Cul Catalyzed Heck Reaction in Aqueous Two-Phase System
【摘要】 以双水相为反应溶剂,丙烯酸酯、苯乙烯与多种芳卤化合物在催化剂碘化亚铜、配体L-脯氨酸的存在下,在较低的温度(75~85℃)下得到了产物,该方法具有反应时间短、产率较高、选择性较好等特点,为该反应及该类化合物的合成提供了一种新方法.产物通过熔点、红外、核磁共振氢谱、碳谱等方法的表征.
【Abstract】 The copper-catalyzed Heck reaction of acrylic ester or styrene with aryl halide gave the coupling products in good to excellent yields in aqueous two-phases system in 75~85℃by using L-proline as a ligand.This method provides a new simple and inexpensive access to the Heck reaction.The structures of the products were confirmed by using spectroscopic techniques such as IR,1H NMR,13C NMR and comparing their melting points with known literature.
