The synthesis of symmetrical and unsymmetrical alkylaminonaphthalic-1,8-N-alkylimides

Symmetrical 4‐n‐alkylamino and 2‐(n‐alkylamino)naphthalic‐1,8‐N‐alkylimides are prepared with primary amines from 4‐ and 2‐halogenonaphthalic‐1,8‐anhydrides in N‐methylpyrrolidinone. 3‐Halogenonaphthalic‐1,8‐anhydrides only react at the anhydride. Unsymmetrical 4‐compounds result by reaction of prim...

Unsymmetrical 4‐compounds result by reaction of primary amines with the anhydride in ethanol and then the 4‐halogeno‐N‐alkyl product in N‐methylpyrrolidinone with primary or secondary amines © 2000 Society of Chemical Industry
