As steric hindrance around the electrophilic center increases, as with isobutyl bromide, substitution is disfavored and elimination is the predominant reaction. en.wikipedia.org

However, electrophilic substitution is relatively facile at the 5-position, including nitration and halogenation. en.wikipedia.org

The steric interaction between the pyrrolidine ring and the electrophilic reagent hinders the attack of the electrophile from the top face. en.wikipedia.org

This allows for strictosidines formation under the subsequent ring closure via electrophilic substitution, as shown in the image to the right. en.wikipedia.org

Reactions of chloroamine include radical, nucleophilic, and electrophilic substitution of chlorine, electrophilic substitution of hydrogen, and oxidative additions. en.wikipedia.org

The mechanism is similar to that of protolysis of alkanes, with an electrophilic insertion into the single bonds of the alkane. en.wikipedia.org

Singlet carbenes with unfilled p-orbital should be electrophilic. en.wikipedia.org

The chemical reaction ranks under electrophilic aromatic substitutions followed by an elimination of water and then a second aromatic substitution. en.wikipedia.org

The first nitration can occur with nitric acid in sulfuric acid, but this deactivates the ring towards further electrophilic substitution. en.wikipedia.org

Halogenation of phenols is faster in polar solvents due to the dissociation of phenol, with phenoxide ions being more susceptible to electrophilic attack as they are more electron-rich. en.wikipedia.org
