Synthesis of Mono and Bis-Substituted Compounds 1-(2-hydroxybenzylidene) Carbonohydrazide and 1, 5-bis(2-Hydroxybenzaldehyde) Carbohydrazone: Study Spectroscopy and X-ray Diffraction

Alioune Fall, Ndiouga Fall, Thierno Moussa Seck, Ibrahima Elhadj Thiam, Ousmane Diouf & Mohamed Gaye · International Research Journal of Pure and Applied Chemistry · 2023

The unsymmetric monocarbonohydrazide Schiff base (H5L1) (1) and the symmetric dicarbonohydrazone (H4L2) (2) were prepared from a monocondensation reaction between carbonohydrazide and 2-hydroxybenzaldehyde, respectively, in 1/1 and 1/2 ratio. The compounds were characterized by e...
