The research activity is focused in the CHEMISTRY OF HETEROCYCLES- CHEMISTRY OF DIAZINES AND DIAZINIUM YLIDES particularly, synthesis, structure, stability, reactivity and properties (biological, electrically, so on). This area of activity present interest both because of the theoretical problems involved (stereochemistry and regiochemistry of cycloaddition reactions etc.) but either of the practical one. My work is of interests in “target” compounds with possible practical application as drugs (anti-AIDS, anti-cancer, anti-tuberculosis, antimicrobial, anti high blood pressure etc.), organic semiconductors, acido-basics indicators, insecticide and pesticide for agriculture, grow up factors for agriculture, liquid crystals in electronics etc. See list of papers and conferances.
