3-bromo-2-trimethylsilyl-1-propene 1c reacts with various electrophiles (aldehydes, a ketone, nitriles, terminal alkynes) in the presence of zinc to give functionnalized vinylsilanes. A three steps synthesis of 2-substituted-4-trimethylsilylfurans from 1c and a nitrile is described. Opening of epoxysilanes with cuprates gave an easy access to α-trimethylsilyl-alcohols.
