Nitration eas
WebbThere are no good, general ways to prepare an aniline (ArNH 2) directly from the parent aromatic (Ar-H) by EAS or related methods, so usually aromatic amines are made by nitration followed by reduction. The two main ways to perform the reduction are: Hydrogenation using hydrogen gas in the presence of palladium on activated charcoal … Webb9 nov. 2024 · Electrophilic aromatic substitution (EAS) reactions proceed through a two-step mechanism. In the first step, the aromatic ring, acting as a nucleophile, attacks an electrophile (E+). This is the slow (rate-determining) step since it disrupts aromaticity and results in a carbocation intermediate.
