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.
