WebAs a rule, both the acylation and alkylation Friedel-Crafts reactions fail when meta-directing deactivators are present. Thus nitrobenzene (a deactivated ring) fails to react in the … WebSubstitution Reactions of Benzene and Other Aromatic Compounds. The remarkable stability of the unsaturated hydrocarbon benzene has been discussed in an earlier section.The chemical reactivity of benzene contrasts with that of the alkenes in that substitution reactions occur in preference to addition reactions, as illustrated in the …
