Recently we have published preparative methods of propargyl silane 1,3-difunctionalization with concomitant silyl shift. The mechanistic concept involves propargylsilane activation with an appropriate electrophile, at which point silyl group undergoes 1,2-silyl shift. This creates an electrophilic carbon center that can react with a nucleophile. Previously examined electrophiles for propargyl silane activation are proton, electrophilic halogens and selenium. Both intramolecular and intermolecular nucleophiles are viable for attacking the electrophilic carbon center.
