This book comprises of latest developments of synthesis, structures, reactivity and applications of Schiff base and their metal complexes. It also highlights the synthesis and structural investigation of new Schiff bases, Cu (II) and Pd (II) complexes. The comprehensive approach on the experimental investigation of selective Cu (II) complexes catalyzed oxidation of sulfide and Pd (II) complexes catalyzed Heck and Suzuki reaction will be fruitful to researchers.
