    Abstract: Treatment of internal alkynes with sodium methoxide in the presence of Pd(OAc)2 and PPh3 in methanol for 48 h gave the reduction products, alkenes or alkanes in good chemical yields. This reaction proceeds through a palladium methanolate complex, followed by β-hydride elimination and reductive elimination.

    Treatment of internal alkynes (0.5 mmol) with sodium methoxide (5 equiv.) in the presence of Pd(OAc)2 (5 mol%) and PPh3 (5 mol%) in methanol for 48 h gave the reduction products, alkenes or alkanes in good chemical yields.
