Abstract
Novel bis(2-fluoro-2,2-dinitroethyl)thionocarbonate, ##STR1## is prepared from two moles of 2-fluoro-2,2-dinitroethanol and two equivats of a strong hydroxyl ion source such as sodium hydroxide or potassium hydroxide in water and one mole of thiophosgene in an organic solvent which may be methylene chloride, chloroform, or 1,2-dichloroethane. A phase transfer catalyst which may be benzyltriethylammonium chloride, tetrabutylammonium chloride, didodecyldimethylammonium bromide, or cetyltrimethylammonium chloride is used to transfer 2-fluoro-2,2-dinitroethoxy ions formed in the water phase to the organic solvent phase where they react with the thiophosgene to form the bis(2-fluoro-2,2-dinitroethyl)thionocarbonate. Bis(2-fluoro-2,2-dinitroethyl)thionocarbonate is useful as an energetic explosive.
