Preparation of sydnoneimines by basic cyclization of N-nitrosoaminoacetonitriles
The results of a kinetic study of the cyclization of N-nitrosoaminoacetonitriles in the presence of tertiary amines are presented. The dependence of the reaction rate on the character of the substituents attached to the nitrogen atom in the starting N-nitrosoaminoacetonitrile, concentration and temperature dependences, and the effect of solvents were established.
