quenching with D2O undergoes deuterio-decupration introducing deuterium exclusively in the vinylic position C-2. As mentioned in the introduction, the use of lower order cuprates such as silylcyanocuprate 1 leads selectively to allylsilanes. Trapping of the intermediate vinylcuprate 2 with α,β-unsaturated
