In the case of 2c, we surmise that the predominance of the keto-enolic monofluorinated product observed here is likely due to the stability of the enol form of 2-fluoro-1,3-cyclohexanedione, previously proposed by Whangbo and Bumgardner.[23] A detailed ab initio study of the keto-enol diketo equilibrium for a series of cyclic 2-fluoro-1,3-diketones is underway and will be published separately.

AB - Silyl enol ethers, obtained by silylation of ketones, are acylated with acetyl tetrafluoroborate to give 1,3-diketones in reasonable yields. The tert-butyldimethylsilyl enol ether of cyclohexanone gives a nearly quantitative yield of acetylcyclohexanone, while the trimethylsilyl enol ethers of cyclohexanone and other ketones give moderate yields of the corresponding 1,3-diketones. The regiospecificity of the reaction was studied with the isomeric silyl enol ethers of 2-methylcyclohexanone.

This phenomenon was reported by Chambers and coworkers, who found that hydration occurred during the preparation of 2,2-difluoro-1,3-cyclohexanedione with dilute fluorine gas in formic acid.[25,26] We found that hydration was reversed when the samples were subjected to high temperatures under vacuum.
