Palladiurn(0)-catalysed transfer hydrogenation of alkynes to cis-alkenes with HCO2H–NEt3
Abstract
Transfer hydrogenation of alkynes using HCO2H–NEt3 as a hydrogen donor in the presence of Pd0-catalyst proceeds highly stereoselecively to afford cis-alkenes in excellent yields, thus providing a practical method for conversion of alkynes to cis-alkenes.
