Fish scale derived hydroxyapatite silica propyl bis aminoethoxy ethane cuprous complex:An efficient hybrid nano catalyst for N-arylation of N-heterocycles with aryl halides

The Ullmann-type N-arylation of N-heterocycles with various aryl halides catalyzed by fish scalederived hydroxyapatite silica propyl bis aminoethoxy ethane cuprous complex (HASPBAEECC) is described. TheN-aryl products were obtained in good yields and the catalyst could be reused for ۵ consecutive runs with nosignificant decline in its reactivity.
