Abstract

Abstract : A new magnetic nanoparticle‐supported Schiff base complex of manganese was prepared via the copper‐catalyzed 'click' reaction of an aminosalicylidene manganese complex bearing terminal alkynyl with azide‐functionalized shell–core magnetic nanoparticles. The as‐prepared catalyst was applied in theoxidation of alcohols to corresponding aldehydes or ketones with high yield and selectivity when the reaction was carried out in dimethylsulfoxide at 110°C for 4 h using tert ‐butyl hydroperoxide as oxidant. Moreover, the catalyst can be easily separated from the reaction mixture using an external magnet and reused five times with no significant loss ofcatalytic activity .
