Studies on the nef reaction induced by organic bases

Abstract
Studies of the Nef reaction in the presence of primary, secondary and tertiary amines have been described. A convenient synthesis of N‐substituted pyrroles and 3,6‐dimethyl‐4‐hydrazinocarbonyl‐5‐(4‐amino‐3‐nitrophenyl)‐pyridazine 16 has been developed.
