Selective reduction of alkynes catalyzed by palladium acetate with sodium methoxide as the hydride source

Add time:09/24/2019    Source:sciencedirect.com

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.
