CF(3)I is being considered by the U.S. Air Force as a replacement for Halon 1301 for fire-extinguishing requirements in unoccupied spaces. The purpose of this study was to determine and evaluate the potential for CF(3)I to produce reproductive toxicity and...
In 2001, Professor William Dolbier, Jr., at the University of Florida reported1 an approach to nucleophilic trifluoromethylation based on the generation of a trifluoromethyl anion using CF3I in the presence of a powerful twoelectron reductant, tetrakis(dimethylamino)ethylene (TDAE)
