Regioselective formation of 1,1-disubstituted allenylsilanes via cross-coupling reactions of 3-tri-n-butylstannyl-1-trimethylsilyl-1-propyne

Abstract

The regioselective Stille cross-coupling reactions of 3-tri-n-butylstannyl-1-trimethylsilyl-1-propyne demonstrate isomerization following the initial transmetalation step resulting in allenyl palladium intermediates for reductive coupling to yield conjugated 1,1-disubstituted allenylsilanes.
