The selective hydrogenation of internal alkynes for Z-alkene stereoisomers is applicable in the petrochemical and pharmaceutical industry. Nickel catalysts are still an interesting alternative low-cost compared with Lindlar or Pd catalysts. This paper evaluates the activity and selectivity of a Ni 1% catalyst in the selective hydrogenation of 3-hexyne modifying the alumina support with a 5 and 10% magnesium precursor with excellent results in conversion values (ca.100%) for the reaction time considered.
