We prepared a highly active Khaya cellulose supported poly(hydroxamic acid) copper nanoparticles by the
surface modification of Khaya cellulose through graft copolymerization and subsequently amidoximation. The Cunanoparticle (0.05 mol% to 50 mol ppm) was selectively
promoted Aza-Michael reaction of aliphatic amines to give the corresponding alkylated products at room temperature in methanol. The supported nanoparticle was easy to recover and reused seven times without significance loss of its activity
