The complex (CF3)3B · NH3 (I) has been prepared both by catalytic hydrogenation of (CF3)3B · NH2CH2C6H5 and by pyrolysis of (CF3)3B · NH2CMe2(CH2)2CHCMe2. Compound I reacts with moisture and DMSO to form a trihydrate (II) and a 1 : 1 solvate (III), respectively. Deprotonation with KOH yields K[(CF3)3BNH2] (IV). The salt IV was alkylated with n-C4F9SO3CH2CF3 to form K[(CF3)3BNHCH2CF3] (V), whose protonation
