Adducts of tetrafluorosilane and secondary amines NHR2(R = Me or Et) react, especially when an excess of tetrafluorosilane is present, with the following dehydrofluorinating agents: LiAlH4(200°); NaBH4(200°); B2H6(190–200°); electropositive metals (350°). The products are corresponding substituted aminofluoro-silanes SiF4–n(NR2)n, (R = Me, n= 1 or 2; R= Et, n= 1). Tetrafluorosilane slowly reacts at
