WebIntroduction of another halogen or unsaturation decreases biological inertness. Boiling points of fluoroalkanes can be estimated from the Kinney equation. The most common method of fluorination, namely electrofluorination, is briefly described and applied to several types of organic compounds. Hydrocarbons give low yields of perfluoroalkanes. Electrochemical fluorination (ECF), or electrofluorination, is a foundational organofluorine chemistry method for the preparation of fluorocarbon-based organofluorine compounds. The general approach represents an application of electrosynthesis. The fluorinated chemical compounds produced … See more The Simons process, named after Joseph H. Simons entails electrolysis of a solution of an organic compound in a solution of hydrogen fluoride. An individual reaction can be described as: R3C–H + HF → … See more ECF has also been conducted in organic media, using for example organic salts of fluoride and acetonitrile as the solvent. A typical fluoride source is (C2H5)3N:3HF.
