Abstract
An efficient solvent-less procedure has been expanded to synthesis primary amides through Beckman rearrangement using Cu(II)/hydroxyl terminated triazine-based dendrimer (Cu(II)/TD) as a proficient heterogeneous nano-catalyst. The Cu(II)/TD nano-catalyst was recognized using TEM, FT-IR, TGA, SEM, EDS, XRD and ICP techniques. The deploying of this new nano-catalyst provides the synthesis of assorted primary amides in outstanding yields through a simple working-up method in a short-term reaction under green conditions in the absence of dangerous and poisonous organic solvents. The Cu(II)/TD catalyst was able to reprocessed and recovered many times without considerable failure of its performance.
