The electrophilic fluorodesilylation of enantioenriched allenylsilanes proceeds with efficient transfer of chirality. The silylationâfluorination of propargylic alcohols occurs with overall retention of stereochemistry, a result consistent with a stereospecific anti SE2â² mechanism for the fluorination step.
