Sodium Hydroxide → 3,3,3-Triethoxyprop-1-yne

Participants

Reaction Steps

A solution of sodium hydroxide (0.14 g, 3.60 mmol) in water (50 mL) was added to a solution of trimethyl-triethoxyprop-1-ynyl-silane (50.0 g, 208 mmol) in ethanol (250 mL). After stirring for 1 hour at room temperature, water was added and the mixture was extracted with ethyl acetate. The organic extracts were dried with magnesium sulfate and the solvent was removed under reduced pressure to give the title compound (20.0 g, 52% yield) as yellow oil. 1H NMR (CDCl3) δ 3.70 (q, 6H, J=8.0 Hz), 2.56 (s, 1H) 1.24 (t, 9H, J=8.0 Hz).
