S-TRIAZINE-DELTA-2-PYRAZOLINE SYNTHESES . 2. DICHLORO-S-TRIAZINE-DELTA-2-PYRAZOLINE REACTION WITH AMINES

This is a further study of the dichloro-s-triazine-DELTA2-pyirazoline behaviour as an amine acylation agent and of the important influential factors, e.g. amine nucleophilic reagent nature, temperature, reation medium. Ammonia, piperidine, cyclohexylamine, methanilic acid, sulpha nilic acid and 4,4'-diaminostilbene were used as amine reagents, estab lishing the dependence between their basicity and the acylation reacti on fields, as well as the influence of the high basicity nucleophilic reagents concurrent reaction.
