The carbamyl fluoride SF5NHC(O)F reacts with both H2O and H2S to give the urea (SF5NH)2CO. Evidence supports that this reaction proceeds through a mechanism involving dehydrofluorination; whereas, the reagents PhLi and PCl5 serve only to dehydrofluorinate SF5NHC(O)F. The ring of the cyclic imide SF5NC(O)CF2CF2C(O) can be readily opened by nucleophiles to give products such as SF5NHC(O)CF2CF2C(O)OH
