Abstract Selective functionalization via cleavage of the C–N bond amines has proven to be challenging partly because its relatively high dissociation energy, even though are abundant and readily available. To meet this challenge, many new transformations based on pre-activation before have been developed. Among them, conversion into quaternary ammonium salts certain advantages, such as easy preparation from primary, secondary, or tertiary amines, well stable storage usage. Although transition metal catalysis frequently applied for developing oxidative addition salts, recent studies shown a dimension by using green electro- photochemical tools. In short review, advances in electro-, photo-, photoelectrochemical driven synthetic applications summarized discussed. 1 Introduction 2 Electrochemical Driven Transformations 3 Photochemical 4 Photoelectrochemical 5 Conclusion Outlook
