    Chemoselective Hydrogenation Reaction of Unsaturated Bonds in the Presence of an <i>o</i>‑Nitrobenzenesulfonyl Group

    No full text
    Chemoselective hydrogenation of unsaturated compounds bearing an <i>o</i>-nitrobenzenesulfonyl (Ns)-amide moiety, affording the corresponding saturated compounds, was accomplished efficiently without loss of the nitro group by using the Pd/MS3A catalyst and a H<sub>2</sub> balloon. Partial hydrogenation of alkynes bearing an Ns group to corresponding <i>cis</i> alkenes was achieved with the combination of the Pd/BN catalyst and an additive (diethylenetriamine or acetic acid)
