Abstract

Anodic fluorination of 4-arylthio-1, 3-dioxolan-2-ones was investigated using various supporting fluoride salts and solvents. Their fluoro-desulfurization took place predominantly in Et4NF· 5HF/CH2Cl2 while the use of Et4NF· 4HF/DME resulted in α-fluorination, without the desulfurization, selectively. Electrolytic solvents affected markedly the product selectivity as compared with supporting fluoride salts. This is the first example of a solvent effect on ...
