碳负载钯催化剂对Heck反应的催化性能

摘要

The catalytic performance of carbon supported palladium catalyst for the Heck reac-tion of phenyl halide and substituted phenyl halide with acrylic acid or styrene was studied .Re-sults show that carbon supported palladium catalyst can effectively catalyze the investigated Heck reactions under a temperature of 80 ℃ and a reaction duration of 8 h in the presence of tetrabutylammonium bromide solvent and tributylamine alkali ,affording a yield of over 80% . Besides ,it can also well catalyze the Heck reaction of substituted phenyl halide with acrylic acid or styrene .%研究了钯碳催化剂对芳基卤和取代芳基卤与丙烯酸和苯乙烯的 H eck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、四丁基溴化铵（TBABr）作为溶剂和三丁胺作为碱的条件下，钯碳催化剂对不同取代芳基卤与丙烯酸和苯乙烯的H eck芳基化反应具有良好的催化性能，产物收率在80％以上。
