In 2007,Portilla, Jaime; Mata, Ernesto G.; Cobo, Justo; Low, John N.; Glidewell, Christopher published 《Two isomeric reaction products: hydrogen-bonded sheets in methyl 4-(5-amino-3-phenyl-1H-pyrazol-1-yl)-3-nitrobenzoate and hydrogen-bonded chains of edge-fused rings in methyl 3-nitro-4-[(5-phenyl-1H-pyrazol-3-yl)amino]benzoate》.Acta Crystallographica, Section C: Crystal Structure Communications published the findings.Recommanded Product: 329-59-9 The information in the text is summarized as follows:
In Me 4-(5-amino-3-phenyl-1H-pyrazol-1-yl)-3-nitrobenzoate, C17H14N4O4, the mols. are linked into complex sheets by a combination of N-H···N, N-H···O, and C-H···O hydrogen bonds. In the isomeric Me 3-nitro-4-[(5-phenyl-1H-pyrazol-3-yl)amino]benzoate, mols. exhibit a polarized mol.-electronic structure and are linked into chains of edge-fused rings by a combination of N-H···O and C-H···O hydrogen bonds. The results came from multiple reactions, including the reaction of Methyl 4-fluoro-3-nitrobenzoate(cas: 329-59-9Recommanded Product: 329-59-9)
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.Recommanded Product: 329-59-9Methyl 4-fluoro-3-nitrobenzoate is used to prepare dimethyl 3-nitro-3′,4-oxydibenzoate by reacting with 3-hydroxy-benzoic acid methyl ester.
