title: Silicon Reagent with Functionalized Tetrafluoroethylene Fragments: Preparation and Coupling with Aldehydes.
abstract: A new fluorinated silicon reagent bearing a functionalized tetrafluoroethylene fragment was prepared from two CF2building blocks: ethyl bromodifluoroacetate and (bromodifluoromethyl)trimethylsilane. The key C-C bond-forming step involves a difluorocarbene addition/cyclopropane rearrangement sequence. The silicon reagent was coupled with aldehydes and reactive azomethines in the presence of potassium fluoride.
