摘要：

Flexible tridentate Lewis acids based on new trisilylmethane scaffolds with three ethynyl groups {Me3SiC[Si(Me)(2)CC-H](3)} and three vinyl groups {Me3SiC[Si(Me)(2)CH=CH2](3)}, respectively, have been synthesised and functionalised by metallation with gallium organyls to yield Me3SiC[Si(Me)(2)CC-GaR2](3) (R = Me, Et). Hydrometallation of the trisilylmethane frameworks with HB(C6F5)(2) and various chlorosilanes afforded flexible poly-Lewis acids equipped with B(C6F5)(2), SiCl3, SiMeCl2 and SiMe2Cl substituents. The reaction of these silicon-containing tridentate Lewis acids with SbF3 led to fluorine-substituted poly-Lewis acids of the type Me3SiC[Si(Me)(2)CH2CH2SiMe3-nFn](3) (n = 1-3). All the compounds were characterised by multinuclear NMR spectroscopy, mass spectrometry, elemental analyses and some by X-ray diffraction.
