N′-(3,4-Dimethoxybenzylidene)acetohydrazide

Abstract

The asymmetric unit of the title compound, C11H14N2O3, contains two independent mol­ecules with close conformations; the C=N—N—C torsion angle is 176.4 (1)° in both mol­ecules. In the crystal, inter­molecular N—H⋯O and C—H⋯O hydrogen bonds link the mol­ecules into chains running along the [01] direction.

N′-(3,4-Dimethoxybenzylidene)benzohydrazide

“…1. The bond lengths and angles are comparable to those observed for N′-(2,4-dimethoxybenzylidene)-3,4,5-trihydroxybenzohydrazide (Alhadi et al, 2009) and N′-(3,4-dimethoxybenzylidene)acetohydrazide (Zhou et al, 2009). The crystal structure is characterized by chains of running along the c-axis.…”

Kinetic and thermodynamic study of inter‐ and intramolecular proton transfer in N′‐acetyl formohydrazide tautomers

“…For example, their crystal structures [33][34][35][36][37][38][39][40][41], vibrational analysis [42], antituberculosis activity [43], citotoxicity [44], magnetic properties [45], voltametric behavior [46] and thermochemical study [47] have been reported. However, only a few researches about theoretical study of simple hydrazides have been reported [48,49] and any report about the investigation of tautomerism in AHs has not been observed.…”
