摘要
We have found that Suzuki-Miyaura-type reactions of dibromoalkenes with arylboronic acids using a hydrazone-Cu catalyst system proceeded smoothly under mild conditions to afford the corresponding internal alkyne derivatives in good yields. Furthermore, we also succeeded in the synthesis of o-allyloxy(ethynyl) benzene derivatives, which are known to be effective precursors of various heterocyclic compounds, through this reaction.
