Environmentally benign, economically feasible, and solvent-free syntheses of series of imines by the condensation of a substituted hydroxynaphthyl ketone with several substituted iodoanilines under grinding approach are described. Imines were further tested for antioxidant activity; most of them show moderate activity. General procedure for the synthesis of imines A mixture of the hydroxyketone 1 (0.01 mol) Zangade et al.
