The new compounds, CF3SF(0)=NCF3 and CF3SF(=NCH3)=NCF3, result from nucleophilic displacement reactions of CF3SF3=NCF3 with water and methylamine, respectively. Higher yields of the di-imine are obtained when CH3N(Si(CH3)3)2 is substituted for CH3NH2. Stable fluoroamines, CF3SF4N(F)Rf (Rf = CF3, C2F
The unusual chemical equilibria F3SSF ⇌ 2 SF2 and CF3SF2SCF3 ⇌ 2CF3SF
