NUCLEOPHILE-INDUCED TRANSFORMATIONS OF 1,2,4-TRIAZINES. 3. ANRORC CONSTRICTION OF THE RING IN THE REACTION OF 6-ARYL-3-DIMETHYLAMINO-1,2,4-TRIAZINE 4-OXIDES WITH KCN

Abstract

Reaction of 6-aryl-3-dimethylamino-1,2,4-triazine 4-oxides with KCN results in constriction of the heterocycle and formation of 3-amino-5-aryl-4-nitrosopyrazoles. Several methods including labelled K13C15N are used to demonstrate that the reaction proceeds through the ANRORC mechanism.
