摘要

A series of carbene complexes [PdBr2 (iPr2-bimy) L](C2–C13) with different types of co- ligands (L) have been tested for their catalytic activities in the carbonylative annulation of 2- iodophenol with phenylacetylene in DMF to afford the respective flavone 2a. Complex C12 with an N-phenylimidazole co-ligand showed the best activity and also afforded high yields when the substrate scope was extended to other aryl or pyridyl acetylenes. In addition, ...
