And the article was published in Organic Letters in 2019. Computed Properties of C8H6FNO4 The author mentioned the following in the article:
A Pd-catalyzed intramol. C-H arylation of nitroarenes has been developed. Nitroarenes bearing tethered aryl groups at the ortho-position can be readily prepared in one step from 2-halonitroarenes by a nucleophilic aromatic substitution (SNAr). Under Pd/BrettPhos catalysis, activations of the C-NO2 bond as well as the C-H bond on arenes generated the corresponding biaryl linkage in moderate to excellent yields. After reading the article, we found that the author used Methyl 4-fluoro-3-nitrobenzoate(cas: 329-59-9Computed Properties of 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.Computed Properties of C8H6FNO4
