Monohydrocyanation of symmetrical azines using potassium hexacyanoferrate(II) as an environmentally friendly cyanide source

Hu, Xiaochun,Li, Hongbo,Yang, Jingya,Li, Zheng

, p. 1786 - 1790 (2014)

The monohydrocyanation of symmetrical azines to synthesize α-hydrazinonitriles using potassium hexacyanoferrate(II) as cyanide source and benzoyl chloride as a promoter under catalyst-free conditions is described. The advantages of this protocol are the environmentally friendly cyanide source, high yield, and simple work-up procedure. Georg Thieme Verlag Stuttgart New York.
