Efficienttransamidation of unactivated carboxamides, phthalimides, formamides and thioamides with amines undersolvent-freeconditions using H-β-zeolite as a green and recyclable heterogeneous catalyst is described. Easy work up, high purity of the products, recyclability and environmentally-friendly nature of the catalyst are the attractive features of the present methodology. This is the first report

with n-octylamine. CeO2 acts as a reusable and effective heterogeneous catalyst for transamidation undersolvent-freeconditions. Transamidation of a variety of amides and amines produced the corresponding N-alkyl amides in high yields. This method provides the first example of a heterogeneous catalyst for transamidation using aliphatic amines as substrates. Characterization of acid–base properties

substitution by the reductants, and (in the case of o-bromonitrobenzene) with a small amount of Ullmann-type coupling of the halide. Copper(I) oxide or the metal were the most effective of the copper species examined, and both dissolved during reaction. Unsaturated substituents, particularly o-NO2, greatly enhanced reducibility. α-Bromo-ketones readily underwent similar reduction. Fission occurred in the
