A cyano group in 1, 2, 4-triaznes, regardless of its position, acted as an effective leaving group in reactions with carbanions. Thus, the reactions gave the corresponding substituted products in place of the compounds formed by addition reaction of carbanions to the cyano group. Grignard reaction of these carbonitriles is also described.
