曲克芦丁-Pd/Ce双金属催化剂对Heck反应催化性能研究

Catalytic Properties of Troxerutin-Pd/Ce Bimetallic Catalyst for Heck Reaction

制备了曲克芦丁-Pd/Ce双金属配合物催化剂,考察了催化剂对芳基卤和取代基芳基卤与丙烯酸的Heck芳基化反应的催化性能.结果表明:在反应温度为80℃、反应时间为8 h、TBABr作为溶剂和三丁胺作为碱的条件下,曲克芦丁-Pd/Ce双金属配合物能够有效地催化Heck芳基化反应,产率达85%以上.该催化剂对不同取代基芳基卤与丙烯酸的Heck反应也有很好的催化性能.

The bimetallic complex of troxerutin-Pd/Ce was synthesized.The catalytic properties of complex were researched for Heck reaction of phenyl halide and substituted phenyl halide with acrylic acid.The results showed that the complex can catalyzed Heck reaction in the conditions of temperature 80 ℃,time 8 h,solvent TBABr,alkali Bu3N,and the yield can reach 85% above.It can also catalyzed the Heck reaction of substituted phenyl halide with acrylic acid well.
