WitrynaA quaternization reaction occurs at this point to produce cations. Cations can be produced in two ways: by quaternization of the amine/phosphane with another haloalkane or by protonation of the amine/phosphane by an acid. Alkylating agents play a critical role in quaternization reactions to produce salts with various anions [39].
