Addition reactions of tetrafluorohydrazine with a number of types of unsaturated nitrogen compounds have been demonstrated to occur in the expected manner. Unsaturated amides, carbamates, isocyanates, nitriles, and nitro compounds were investigated. Diallylic- substituted nitrogen compounds formed cyclic bis (difluoramines) as well as the tetrakis (difluoramines). Only the nitro compounds failed to react.
