- Fluorination of organochlorophosphorus compounds with alkali metal salts of perfluorinated complex anions. Part 2
-
Alkali metal salts of perfluorinated complex anions were used to fluorinate a few selected organochlorophosphorus compounds in the presence and absence of a multifunctional etheral solvent. Together with oxidative products, low to moderate yields of the desired monofluorinated products were obtained.
