    Abstract

    Abstract A facile preparation of nitrones has been achieved by use of unsupported nanoporous gold (AuNPore) as a heterogeneous catalyst through aerobic oxidation of N,N-disubstituted hydroxylamines with molecular oxygen as an oxidizing agent under mild conditions. A variety of amines were oxidized to the corresponding nitrones in high chemical yields. The catalyst is robust enough to be reused without leaching.
