Fluoroalkyl alkyl carbonates and fluorosubstituted carbamates which are suitable as additives or solvents in lithium ion batteries are prepared from fluoroalkyl fluoro formates and the respective alcohol or amine. Methanol is the preferred alcohol, dimethylamine and diethylamine are preferred amines. Fluoromethyl methyl carbonate is the preferred compound to be produced. Fluoroalkyl fluoro formates can be prepared from aldehydes and carbonyl fluoride.
