Abstract

A flow electrochemical method towards the synthesis of N‐nitroso compounds from secondary amines using cheap and readily available sodium nitrite has been developed. Sodium nitrite dissolved in aqueous acetonitrile made additional electrolytes unnecessary. This mild and straightforward approach made the use of acids or other harsh and toxic chemicals redundant. This procedure was applied to an assortment of cyclic and acyclic secondary amines (27 examples) resulting in yields of N‐nitrosamines as high as 99 %. To demonstrate the practicality of the process, scaled‐up reactions were performed. Finally, selected products could be purified by using an in‐line acidic extraction.
