Síntesis de Compuestos de Cu (II) y Zn (II) con ligandos Salen, caracterización estructural y evaluación de la actividad fungistática contra Botrytis cinérea DMS 5144; y Fusarium sp

Abstract

The synthesis of new materials with antifungal properties, of wide interest at agroindustrial and pharmaceutical areas due to the multiple resistances that the fungi present to the chemical control currently offered in the market. As a support strategy for this problematic situation, it is proposed to carry out various organic tests of Schiff base compounds, as ligands in coordination compounds with sales of copper (II) and zinc (II). The success of the synthesis processes can be verified by molecular characteristics using several instrumental analytical techniques such as: Infrared Spectroscopy (IR), Mass Spectrometry (MS), Nuclear Magnetic Resonance (NMR) and Visible Ultraviolet (UV-Vis), crystallographic characterization by Diffraction of X-ray powder, structural characterization by study of monocrystals. Finally, the following were evaluated as possible fungistic agents on the strains of phytopathogenic interest in the region and the country as: Botrytis cinerea DMS 5144; main causative agent of gray mold in fruits and Fusarium sp; causal agent of anthracnose and rotting of vegetables and fruits.
