The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 2-Furoic hydrazide( cas:3326-71-4 ) is researched.Electric Literature of C5H6N2O2.Sylla-Gueye, Rokhaya; Thiam, Ibrahima Elhadji; Orton, James; Coles, Simon; Gaye, Mohamed published the article 《Crystal structure of N′-[4-(dimethylamino)benzylidene]furan-2-carbohydrazide monohydrate》 about this compound( cas:3326-71-4 ) in Acta Crystallographica, Section E: Crystallographic Communications. Keywords: furoic hydrazide dimethyl aminobenzaldehyde crystal structure; crystal structure; furoic acid; hydrazide; hydrazone. Let’s learn more about this compound (cas:3326-71-4).
The condensation of 2-furoic hydrazide and 4-dimethyl aminobenzaldehyde in ethanol yielded a yellow solid formulated as the title compound, C14H15N3O2·H2O. The crystal packing is stabilized by intermol. O(water)-H···O,N(carbohydrazide) and N-H···O(water) hydrogen bonds, which form a two-dimensional network along the bc plane. Addnl. C-H···O interactions link the mols. into a three-dimensional network. The dihedral angle between the mean planes of the benzene and the furan ring is 34.47 (6)°. The carbohydrazide moiety, i.e., the C=N-N-C=O fragment and the benzene ring are almost coplanar, with an angle of 6.75 (9)° between their mean planes.
