Synthesis and antioxidant activities of Schiff bases and their complexes: a review

Schiff bases, named after Hugo Schiff, are aldehyde-or ketone-like compounds in which the carbonyl group is replaced by imine or azomethine group. They arewidely used for industrial purposes and also have a broad range of applications as antioxidants. An overview of antioxidant applications of Schiff bases and their complexes is discussed in this review. A brief history of the synthesis and reactivity of Schiff bases and their complexes is presented. Factors of antioxidants are illustrated and discussed. Copyright (C) 2016 John Wiley & Sons, Ltd.
