Csingle bondN\ cross coupling reaction\ is very important in synthesis of pharmaceuticals,\ natural products,\ agrochemicals, fine chemicals and functional materials. Traditionally,\ palladium\ or copper metals are used for Csingle bondN coupling reaction. As palladium is expensive, we developed cobalt immobilized carbon-based nano-catalyst Co@CC for Csingle bondN coupling. In this work, we synthesized non-noble metal-based Co@CC nano-catalyst by\ carbonization\ of glucose, it{\textquoteright}s functionalization followed by immobilization of cobalt on the surface of the catalyst. The catalyst was well characterized. The Csingle bondN cross coupling reaction of various aryl\ halides\ \& amines using Co@CC nano-catalyst was optimized for solvent, reaction temperature \& catalyst\ concentration conditions. The catalyst showed high catalytic activity for Csingle bondN coupling of various aryl halides \& amines to form aryl amines in good to excellent yield up to 91\ \% in\ sulfolane\ as a solvent at 150\ {\textdegree}C. The catalyst showed recyclability up to 5 times. The method developed for Csingle bondN coupling reaction was noble metal free, ligand free, recyclable, sustainable, economical \& environmentally friendly.
