Resumen
Se sintetizaron dos nuevos derivados 5-nitro y 7-nitrofenantro[9,10-c][1,2,5]tiadiazol 2,2-dióxido, por nitración convencional del compuesto padre, con un redimiendo global ca. 55%. Las estructuras de los dos isómeros se dilucidaron por medio de estudios de difracción de rayos-X. Por reducción química de ambos compuestos con cianuro de litio se obtuvieron aniones-radicales estables derivados de los mismos, los cuales se caracterizaron espectroscópicamente (UV-Vis, EPR). Los derivados nitrados se ensayaron como inhibidores de la corrosión de Cu en H2SO4 0,25 M, lográndose una eficiencia de inhibición máxima del 84 %. Se efectuaron ensayos de citoxicidad de los derivados nitrados, encontrándose que para concentraciones inferiores a 10,8 M no presentan efectos desfavorables en la línea celular CHO-K1
Two new 5-nitro and 7-nitro derivatives were synthesized by conventional nitration procedure of phenanthro [9,10-c] [1,2,5] thiadiazole 2,2-dioxide with ca. 55% of global yield. Their structures were elucidated by of X-ray diffraction studies. Stable radical-anions were obtained by chemical reduction of the nitrated derivatives with lithium cyanide, which were characterized by spectroscopic measurements (UV-Vis, EPR). Nitro derivatives were tested as corrosion inhibitors for Cu in 0.25 M H2SO4 with a maximum of inhibition efficiency of 84%. Cytotoxicity assays of the nitro compounds were performed and it was found that for concentrations lower than 10.8 M they have not adverse effects on the cell line CHO-K1.
