Fluorination of ketones was achieved by the reaction of silyl enol ethers with iodotoluene difluoride in the presence of BF 3 .OEt 2 and a Et 3 N.HF complex.
A p-toluenesulfonic acid catalyzed fluorination of α-branched ketones for the construction of fluorinated quaternary carbon centers has been developed, featuring a broad substrate scope, environmentally benign reaction conditions, and operational simplicity.
