Reaction of 1,1-diiododinitroethylene with fluoride. Preparation of 1,1,1-trifluorodinitroethane derivatives.
摘要:
The reaction of 1,1-diiododinitroethylene with tetrabutylammonium fluoride gave the tetrabutylammonium salt of 1,1,1-trifluorodinitroethane. Acidification of this salt in ethyl acetate, extraction of tetrabutylammonium salts with water, and addition of sodium bicarbonate led to the isolation of the sodium salt of 1,1,1-trifluorodinitroethane. The reaction of formaldehyde with the tetrabutylammonium salt gave 3,3,3-trifluoro-2,2-dinitropropanol, which was converted to its formal with trioxane and sulfuric acid.
