Catalytic transfer hydrogenation over bimetallic lanthanide (Eu or Yb)-containing catalysts using NH3 as a hydrogen donor
Abstract
Catalytic transfer hydrogenation of ethene and buta-1,3-deine with the aid of ammonia as a hydrogen donor is greatly enhanced by lanthanide (Ln)-promoted catalysts (Ln–Ni/SiO2, Ln–Ru/C, Ln–Cu/SiO2 and Ln–Ag/ZrO2), prepared by the reaction with Eu or Yb metal dissolved in liquid ammonia.
