In 2013,Cortes, Edwar; Abonia, Rodrigo; Cobo, Justo; Glidewell, Christopher published 《Hydrogen-bonded sheet structures in methyl 4-(4-chloroanilino)-3-nitrobenzoate and methyl 1-benzyl-2-(4-chlorophenyl)-1H-benzimidazole-5-carboxylate》.Acta Crystallographica, Section C: Crystal Structure Communications published the findings.COA of Formula: C8H6FNO4 The information in the text is summarized as follows:
In Me 4-(4-chloroanilino)-3-nitrobenzoate, C14H11ClN2O4, (I), there is an intramol. N-H···O hydrogen bond and the intramol. distances provide evidence for electronic polarization of the o-quinonoid type. The mols. are linked into sheets built from N-H···O, C-H···O and C-H···π(arene) hydrogen bonds, together with an aromatic π-π stacking interaction. The mols. of Me 1-benzyl-2-(4-chlorophenyl)-1H-benzimidazole-5-carboxylate, C22H17ClN2O2, (II), are also linked into sheets, this time by a combination of C-H···π(arene) hydrogen bonds and aromatic π-π stacking interactions. In the experimental materials used by the author, we found Methyl 4-fluoro-3-nitrobenzoate(cas: 329-59-9COA of Formula: C8H6FNO4)
Methyl 4-fluoro-3-nitrobenzoate(cas: 329-59-9) belongs to methyl benzoate. Methyl benzoate reacts at both the ring and the ester, depending on the substrate. Electrophiles attack the ring, illustrated by acid-catalysed nitration with nitric acid to give methyl 3-nitrobenzoate.COA of Formula: C8H6FNO4
