The reaction of (F 3 C)Cl 2 SiCl 3  with the lithiated hydrazine LiN(Me)NMe 2  gives the compound (F 3 C)Cl 2 SiN(Me)NMe 2  (1) and in traces Cl 3 SiN(Me)NMe 2  (2). The reactions with LiN(SiMe 3 )NMe 2  and LiONMe 2  give (F 3 C)Cl 2 SiN(SiMe 3 )NMe 2  (4) and (F3C)Cl 2 SiONMe 2  (5), respectively. The compounds were characterised by multinuclear solution NMR, gas-phase IR spectroscopy and mass spectrometry. Information about conformational preferences of 1 and 4 can be extracted by comparing experimental IR spectra with those calculated by quantum chemical methods (B 3 LYP/6-311G**). The former show the gas phase of the β -donor-acceptor silanes 1 and 4 to be dominated by the anti conformations, while the calculations show a preference for the gauche conformers. The crystal structure of Cl 3 SiN(Me)NMe 2  (2) has been determined. The solid-state structures of the Ruppert reagent F 3 C-SiMe 3  (1) and its chlorine analogue F 3 C-SiCl 3  (2) have also been determined by X-ray diffraction of single crystals grown by in situ techniques.
