Abstract

The novel branched oligosilyltriflates of formula [TfO(Me3Si)2Si]2E (2a–d) [E = 0 (2a), SiMe2 (2b), GeMe2 (2c), SiMe2–SiMe2 (2d)] and [TfO(Me3Si)2SiSiMe2]3SiMe (9) have been prepared by the protodesilylation of [Ph(Me3Si)2Si]2E (1a–c), [H(Me3Si)2Si]2E (5d) and [Ph(Me3Si)2SiSiMe2]3SiMe (8) using TfOH (CF3SO3H) as reagent in almost quantitative yields. The crystal structure of 2b is reported.
