Facile and efficient one-pot synthesis of 2-phenyl-1H-phenanthro## [9,10-d]imidazole derivatives using magnetic Co doped NiFe2O4 nanocomposite as a heterogeneous and recyclable catalyst

A simple and efficient procedure for the synthesis of 2-phenyl-1H-phenanthro## [9,10-d]imidazole derivatives via the condensation of phenanthrene-9,10-dione with various benzaldehydes and ammonium acetate by using the magnetic Co doped NiFe2O4 nanoparticles has been developed. The magnetic nanocatalyst was easily separated with the aid of an external magnet and reused at least four times without any loss of its high catalytic activity. Excellent product yields, solvent free conditions, very short reaction times and simple magnetically work-up are other significant advantages of this method.
