Aromatic Nucleophilic Substitution Reactions of 1-Dialkylamino-2,4-dinitronaphthalene with Primary or Secondary Amines in Organic Solvents: Facile Amine-Amine Exchange

Sekiguchi, Shizen,Horie, Tohru,Suzuki, Tohru

, p. 698 - 700 (1988)

The dialkylamino group, (e.g., dimethyl-, diethyl-, and N-n-butyl-N-methylamino, piperidino, and pyrrolidino) of 1-dialkylamino-2,4-dinitronaphthalenes is rapidly replaced by primary amines, particulary in dimethyl sulphoxide; however, substitution does not occur for secondary amines except in the case of pyrrolidine.
