                                This transformation include alkylations with other classes of activated alkyl halides of synthetic interest.

                                Common alkylations and acylations, such as Friedel–Crafts alkylation or acylation, usually fail for pyridine because they lead only to the addition at the nitrogen atom.

                                Different classes of reactions might not fit the peripheral attack model, as reactions such as epoxidations, hydroxylations, alkylations , and reductions all proceed through different transition states.

                                So, same idea: azide is a synthetic equivalent for ammonia, and it lets us do the reaction, a single substitution of our leaving group, without having multiple substitutions taking place, or multiple alkylations . 3016
