The reagent 1- hydroxy-2-acetonaphthone (HAN), its Schiff bases, hydrazones and their metal chelates represent an important class in coordination chemistry and pigment industry. These compounds also possess excellent bacteriostatic properties in vitro against microorganisms, facilitate the iron mobilization from 59Fe labelled reticulocytes and also have a remarkable anticancer effect in tumour growth and antileukemic activity. Thus, the work in this book is focused on the geometry, redox properties, nature, kinetics and mechanism of the electrode couples of HAN, its Schiff bases and...
