Abstract

Abstract : Well defined Ni nanoparticles stabilized with N-heterocyclic carbenes have been synthesized through decarboxylation of a zwitterionic CO2 adduct and they selectively hydrogenate internal alkynes into ( Z )-alkenes under mild reaction conditions. Abstract : Well defined Ni nanoparticles (NiNPs) stabilized with N-heterocyclic carbenes (NHCs) have been synthesized through a new methodology involving the decarboxylation of a zwitterionic CO2 adduct. Their catalytic performance was tested in the partial hydrogenation of alkynes into ( Z )-alkenes under very mild reaction conditions (50 °C and 5 bar H2 pressure), providing excellent activities and selectivities.
