palladium-catalyzed construction of ketones via Suzuki-Miyaura reaction using acid fluorides is described. In contrast to typical acyl electrophiles such as acid chlorides, acid fluorides are uncommon acyl electrophiles to use in boron-based coupling probably due to a high level of stability toward nucleophiles. This first attempt to use acid fluorides as a coupling partner with boronic acid allowed highly

Functionalized cyclohexanones are formed in excellent yield and diastereoselectivity from a phasetransfercatalyzed double addition of active methylene pronucleophiles to nonsymmetrical divinyl ketones.
