Electrolytic partial fluorination of organic compounds. Part 50: Highly selective anodic mono- and difluorination of 4-phenylthiomethyl-1,3-dioxolan-2-one and its synthetic application

Anodic fluorination of 4-phenylthiomethyl-1,3-dioxolan-2-ones was successfully carried out to provide the corresponding α-mono- and α,α-difluorinated products selectively, depending on the amount of the electricity passed. The fluorination was also greatly affected by solvents, temperature and current densities. The fluorinated products were readily converted into the corresponding fluorinated allyl alcohol and diols by treatment with an alkaline solution.
