Abstract<\/strong>
Since 1928, industrial activities of Crotone have been characterized by the presence of the most important Italian chemical industries. The first production was of sulfuric acid, used for extraction and processing of phosphorite rocks rich of 238<\/sup>U and 232<\/sup>Th. [1] The trial was the basis to produce phosphoric acid, useful for fertilizers, detergents, feed, food additives and pesticides. [2,3] The industrial waste could create a problem from an environmental impact point of view if it is not possible to enhance its structural chemical-physical characteristics. The conversion of waste materials into valuable products or green chemicals using green chemistry principles is an important goal to promote an increasingly eco-sustainable society.
In the present study, the performance of industrial wastes as the fumace slag was investigated for the synthesis one-pot of a heterocyclic classes of organic compounds biologically active as 4-quinolones (Figure 1). [4] \u00a0
