“green” catalyst. The catalyst was synthesised 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 characterised by FT-IR, far IR, CHN, XRD, TGA, and ICP techniques. CAEA is shown to be an effective and reusable heterogeneous catalyst for the transamidation of carboxamides with amines under solvent-free

same boat: Tandem rearrangement/N‐alkylation reactions in the presence of a Ru/Ir dual‐catalyst system affords the desired N‐alkylated amines in good‐to‐excellent yields with no intermediate amides or over‐alkylated N,N‐dialkylated amides. This environmentally friendly tandem reaction employs readily available starting materials, affords excellent selectivities for the N‐alkylated amides, and shows
