Silanes undergo this reaction mechanism in an ipso fashion.
Partial rate factors quantify the reactivity of compounds through this mechanism. The Wheland intermediate forms during this mechanism, which has a partitioning effect because both steps are rate-determining. Silanes undergo this reaction mechanism in an ipso fashion. Methyl red and methyl orange are synthesized in a variant of it called diazo coupling. The intermediate of this mechanism is an arenium cation. Sulfuric acid protonates nitric acid to facilitate nitration through this mechanism. In this mechanism, pi donors favor ortho or para substitution. In the presence of a Lewis acid, bromine will react with toluene under this mechanism, not addition. For 10 points, name this mechanism exemplified by the Friedel-Crafts reaction, in which an electron-deficient species attacks benzene.
Partial rate factors quantify the reactivity of compounds through this mechanism.
electrophilic aromatic substitution [or EAS; or SEAr; prompt on substitution or other partial answers; prompt on Friedel-Crafts alkylations or acylations; prompt on diazo coupling]
