The present study reports the preparation and characterization of Ce(III) immobilized on an aminated epichlorohydrin-activated agarose matrix (CAEA) as a green catalyst. The catalyst was synthesized by the reaction of the epichlorohydrin-activated agarose matrix with ammonia solution, which was then treated with Ce(NO3)3·6H2O. The catalyst (CAEA) was characterized by FT-IR, far IR, elemental anal., XRD, TGA and ICP techniques. CAEA was found to be an effective and reusable heterogeneous catalyst for the transamidation of carboxamides with amines under solvent-free conditions. The catalyst was successfully applied to the synthesis of a wide range of aromatic and aliphatic amides. High efficiency, mild reaction conditions, easy work-up and simple separation were the important advantages of this catalyst. In the experiment, the researchers used many compounds, for example, 3,4-Dichlorobenzamide (cas: 2670-38-4Recommanded Product: 2670-38-4).
3,4-Dichlorobenzamide (cas: 2670-38-4) belongs to amides. Compared to amines, amides are very weak bases and do not have clearly defined acid–base properties in water. On the other hand, amides are much stronger bases than esters, aldehydes, and ketones. Ionic, or saltlike, amides are strongly alkaline compounds ordinarily made by treating ammonia, an amine, or a covalent amide with a reactive metal such as sodium.Recommanded Product: 2670-38-4
