    Síntesis y caracterización de hidrazonas obtenidas a partir de 1,2 y 1,4-naftoquinona con 2,4-dinitrofenilhidracina
    (Universidad de Los Andes, 2021) Jesús Ramón Briceño Barrios; Marietta Vizcaya; Freddy A. Carrillo; Gerzón E. Delgado
    In this work, the results of the synthesis and characterization of 1,2- and 1,4-naphthoquinone derivatives with 2,4-dinitrophenylhidrazine in alcoholic solution are presented. The products [1] and [2] were characterized by FT-IR, UV-visible and H1-NMR spectroscopy and X-ray diffraction. The spectroscopic analyzes indicate the formation of the expected hydrazones. X-ray powderdiffraction study indicated that both compounds crystallizes in monoclinic cells, space group P21/c andunit cell parameters: a =16.3541(7) A, b =12.8648(6) A, c =6.9195(1) A, s =100.140(2)°, V =1433.08(9) A3, an-da =7.3274(2) A, b =16.3523(7) A, c =11.1187(5) A, s =99.266(4)°, V =1314.86(9) A3, for [1] and [2] derivatives, respec-tively.
