Abstract
Abstract Trifluorotrimethylsilane reacts with acylsilanes to give the corresponding difluoroenoxysilanes via the Brook rearrangement of the alcoholate adducts. The difluoroenoxysilane reacts in situ with various types of electrophilic substrates, leading to gem-difluoro functionalized derivatives in a one-pot methodology. This paper describes reactions with Michael acceptors, prenyl, benzyl and glycosyl donors leading to 2,2-difluoro-1,5-diketones, 4,4- or 6,6-difluorocyclohexenones, o- or p-fluorophenols, difluoro analogues of terpenes, and difluoro-C-glycosides.
