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.
