In run 1 (control), 5 ml of 2.2 molar KOCF(CF3)2 in anhydrous DMF was added to a reaction vessel and diluted to 5.0 ml with anhydrous DMF. The reaction vessel consisted of a 50 ml round-bottom, three-neck flask which was equipped with a dropping funnel, an inlet tube with a safety trap, and an exit tube with a -80° C. cooled trap. Tetranitromethane (1.0 g, 5.10 mmoles) was placed in the dropping funnel and diluted with 10 ml of DMF. The system was flushed with nitrogen at 40 cc/min for 2 to 3 minutes. The C(NO2)4 -DMF solution was added to the KOCF(CF3)2 at ambient temperature. Fluorotrinitromethane yields and tetranitromethane conversions were obtained by gas-liquid chromatographic analyses of the reaction mixture as a function of reaction time.
