title: N,N-difluorotris(tert-butyl)silylamine-the first organosilyl difluoroamine. Synthesis and computational studies.
abstract: The synthesis and characterization of the first stable trialkyl(difluoroamino)silane, R3SiNF2, as well as of R3SiNHF and R3SiN(CH3)F in moderate yields are reported. The (difluoroamino)silane has promise as a new synthon for the introduction of the -NF2 group into a variety of electrophilic inorganic and organic substrates. Activation barriers and relative energies were calculated for the unimolecular decompositions of Me3SiCF3 and t-Bu3SiNF2 using density functional theory (B3LYP/6-31G). The calculated activation energies confirm the long-assumed kinetic stability of Me3SiCF3.
