supporting information, p. 4222 - 4227 (2019/06/13)
Herein we disclose a deoxyfluorination of alcohols with an electrophilic fluorine source via visible-light photoredox catalysis. This radical-mediated C–F coupling is capable of fluorinating secondary and tertiary alcohols efficiently, complementing previously reported nucleophilic deoxyfluorination protocols.

The invention discloses a method for synthesizing 4-fluorocyclohexanone. The method comprises steps as follows: under the alkaline condition, 1,4-cyclohexanedione monoethylene ketal and a fluorinatingagent are subjected to highly selective reaction, and 8-fluoro-1,4-dioxaspiro[4.5]deca-7-ene is produced; 8-fluoro-1,4-dioxaspiro[4.5]decane is prepared from 8-fluoro-1,4-dioxaspiro[4.5]deca-7-ene and hydrogen under the action of a palladium-carbon catalyst; 8-fluoro-1,4-dioxaspiro[4.5]decane is subjected to deprotection with added acid, and 4-fluorocyclohexanone is obtained. According to the method, 1,4-cyclohexanedione monoethylene ketal which is widely sourced and low in cost is taken as a reaction raw material, a high-purity intermediate can be obtained maximumly in each reaction, so thatthe total yield of the whole reaction is high, purity of a final product is up to 98%, the economic benefit is quite remarkable, less environmental pollution is produced, and the method is particularly suitable for large-scale industrial application and popularization.
