WebA nucleophilic aromatic substitution is a substitution reaction in organic chemistry in which the nucleophile displaces a good leaving group, such as a halide, on an aromatic ring. … WebAryl halides are relatively unreactive toward nucleophilic substitution reactions. This lack of reactivity is due to several factors. Steric hindrance caused by the benzene ring of the aryl halide prevents S N 2 reactions. Likewise, phenyl cations are unstable, thus making S N 1 reactions impossible. citic bank中信银行個人網銀
