text] A cationic palladium complex catalyzed addition of arylboronic acids to nitriles to yield aryl ketones with moderate to good yields was developed. A one-step synthesis of benzofurans from phenoxyacetonitriles under the catalysis of [(bpy)Pd+(micro-OH)]2(-OTf)2 or [(bpy)Pd2+(H2O)2](-OTf)2 was developed which showed that the cationic palladium catalyst is highly active for these addition reactions
[结构:见正文]开发了一种阳离子钯络合物,可将芳基硼酸加成至腈中,从而制得中等至良好收率的芳基酮。研究表明,在[(bpy)Pd +(micro-OH)] 2(-OTf)2或[(bpy)Pd2 +(H2O)2](-OTf)2的催化下,由苯氧基乙腈一步合成苯并呋喃阳离子钯催化剂对这些加成反应具有很高的活性。
