Eckert, Timothy; Harmeyer, Grace; Legate, Steven; Mathe, Steven published the artcile< A Rationale for the Ortho Effect in Electrophilic Aromatic Substitutions>, COA of Formula: C7H4BrF3, the main research area is electrophilic aromatic substitution ortho effect.
The ortho effect arises in certain electrophilic aromatic substitutions when a meta director is meta to an ortho/para director. Among the three expected isomer products, only the two isomers ortho to the meta director were produced normally. To find an explanation for the ortho effect, nitrations of two properly substituted benzenes were explored. Evidence supported an explanation based on resonance involving the meta director.
Letters in Organic Chemistry published new progress about Electrophilic aromatic substitution reaction. 401-78-5 belongs to class bromides-buliding-blocks, and the molecular formula is C7H4BrF3, COA of Formula: C7H4BrF3.
