Sodium persulfate-promoted site-selective synthesis of mononitroarylamines under transition-metal-free conditions
A practical preparation of nitroarylamines from protected arylamines was herein disclosed. In this system, sodium nitrite acted as a nitration reagent in the presence of sodium persulfate without any transition-metal catalysts. This efficient site-selective protocol took place at room temperature for a short time through a free radical pathway.
SYNTHESIS OF UNSYMMETRICAL 1,4-NAPHTHOQUINONE DIIMIDES
The reaction of 4-nitronaphthylamine with methane-, benzene-, and p-toluenesulfonyl chlorides in pyridine gave N,N-diacyl-4-nitronaphthylamines, which were converted by alkaline hydrolysis into N-acyl-4-nitronaphthylamines.With benzoyl chloride the reacti
