果胶负载钯催化剂的制备及Suzuki反应催化性能
Preparation and Suzuki Reaction Performance of Pectin-supported Palladium Catalyst
摘要
Abstract
To discover new heterogeneous palladium catalyst in organic synthesis, pectin, which was extracted form citrus peel, was used as supporter for the preparation of pectin-supported palladium catalyst. The pectin-supported palladium catalyst was applied to Suzuki cross-coupling reaction between sodium tetraphenylborate and aryl bromides. The results revealed that all four aryl groups of sodium tetraryylborate could be efficiently utilized in the Suzuki cross-coupling reactions in an atom-efficient way in the presence of Et3 N as base in PEG 400/H2 O at 110 ℃ in open air, providing excellent yields of the corresponding functionalized biaryls within 1 h. The present protocol has the advantages highly efficient, high yield, mild condition, short reaction time, as well as the catalyst can be recycled and reused.关键词
