An alumina-supported silver catalyst was investigated in the one-pot reductiveamination of aldehydes with nitroarenes in a continuous flow reactor using molecular hydrogen as a reducing agent. A series of secondary amines containing alkyl, OH, OCH3, Cl, Br and CC groups was synthesized in good to excellent yields. The yield of the secondary amine depends on the rate of formation of an intermediate

Two birds with one auric stone: The title system acts as a highly efficient heterogeneous catalyst for the one‐pot tandemsynthesis of imines or oximes from alcohols and the corresponding amines under mild conditions (see scheme; HAP= hydroxyapatite).

formation of substituted amines from nitroaromatics and carbonyl compounds through a series of consecutive steps which involves the reduction of nitro group to amine, the formation of an imine or iminium ion intermediate, followed by in situ reduction to an alkylated amine of higher order in a single operation. Solid complexes result active and recyclable catalysts and no deactivation was observed
