The title carbenoid reagent was generated by treatment of dibromofluoromethyl(t-butyl)dimethylsilane with butyllithium in THF at -78 degrees C and was allowed to react with aldehydes and ketones to give 1-fluoro-1-silyloxiranes in good yields. Alkylation of the silyl-substituted carbenoid was also achieved efficiently in good yields. (C) 1997 Elsevier Science Ltd.
