DMSO–allyl bromide: a mild and efficient reagent for atom economic one-pot <i>N</i>-allylation and bromination of 2°-aryl amines, 2-aryl aminoamides, indoles and 7-aza indoles
A mixture DMSO–allyl bromide has been developed as a reagent for an atom economic one-pot N-allylation and aryl bromination under basic conditions. Utilizing this reagent, N-allylation–bromination of a number of 2°-aryl amines, aryl aminoamides, indoles, and 7-aza indoles has been achieved. The scope of the substrates and limitations, the synthetic utility of the products, and a plausible reaction
of magnetic graphene oxide (MGO) with phenanthroline type ligand. The catalyst was characterized by several characterization methods and used as an effective magnetic heterogeneous nanocatalyst for the N-arylation of 2-amino-N-phenylbenzamide. Cu@Phen@MGO catalyst showed very good efficiency in base-free Chan–Evans–Lam coupling of arylboronic acid with 2-amino-N-phenylbenzamide at room temperature.
