Semihydrogenation of α,β-unsaturated ynoates and -ynones bearing a γ-alkoxy group can be performed using triphenylphosphine and water. α,β-Unsaturated ynoates were reduced to a mixture of cis and trans α,β-unsaturated enoates, whereas, ynones were reduced to trans α,β-unsaturated enones as the only products.
带有 γ-烷氧基的 α,β-不饱和 ynoates 和 -ynones 的半氢化可以使用三苯基膦和水进行。α,β-不饱和烯酮被还原为顺式和反式α,β-不饱和烯酮的混合物,而炔酮被还原为反式α,β-不饱和烯酮作为唯一的产物。
