A number of new magnesium and lithium silyl reagents were prepared and shown to be outstanding nucleophiles in reactions with industrially relevant fluoroolefins. These reactions result in a net transformation of either sp2 or sp3 C?F bonds into C?Si bonds by two modes of nucleophilic attack (SNV or SN2′). The methods are mild, proceeding with high chemo- and regioselectivity. Mechanistic pathways are described that lead to new substitution patterns from HFO-1234yf, HFO-1234ze, and HFO-1336mzz, previously inaccessible by transition metal catalyzed difluorosilylation routes.

The reaction of 3,3,3-trifluoropropenes with disilane/tetrabutylammonium fluoride or silyllithium reagent gives γ,γ-difluoroallylsilanes which afford gem-difluoroallyl adducts of aldehydes and ketones with the aid of a catalyst such as potassium t-butoxid
