General description
(Bromodifluoromethyl)trimethylsilane (TMSCF2Br) is commonly used as a source to generate dilfluorocarbene. TMSCF3 (Ruppert–Prakash reagent) and BBr3 undergoes fast halogen–exchange reaction to form MSCF2Br.
Application
(Bromodifluoromethyl)trimethylsilane may be used in the preparation of:
- gem-difluorocyclopropa(e)nes
- O-, S-, N-, and P-difluoromethylated compounds
- (chlorodifluoromethyl)trimethylsilane
As reported by Hu and co-workers, (Bromodifluoromethyl)trimethylsilane is a highly useful reagent for the formation of difluoromethene-containing 3-membered rings and can also difluoromethylate heteroatoms with the assistance of alkaline bases, most effectively KOH.
