Au(PPh3)NTf2 is needed to convert readily accessible propargylic acetates into versatile linear alpha-iodoenones in good to excellent yields. This reaction is easy to execute and has broad substrate scope. Good to excellent Z-selectivities are observed in the cases of aliphatic propargylic acetates derived from aldehydes.
仅需2 mol%的Au(PPh3)NTf2,即可将容易获得的
