摘要：

Aromatic C-H borylation using [IrCl(COD)](2) and 2.2'-bipyridinedicarboxylic acids was studied. 2,2'-Bipyridine-4,4'-dicarboxylic acid was complexed with [IrCl(COD)](2) in the presence of bis(pinacolato)diboron. The resulting iridium catalyst could be readily separated from the reaction mixture by simple filtration, and the recovered catalyst under a nitrogen atmosphere was still active and could be reused more than 10 times.
