# Converting phenol to para-nitrophenol via nitrosophenol

Our class 12 text book says that if we treat phenol with mixture of concentrated $$\ce HNO_3$$ and $$\ce H_2SO_4$$, instead of nitration, the ring is oxidized to quinone.

So, the book proposes that we should treat phenol with $$\ce NaNO_2$$ and $$\ce HCl$$ to yield 4-nitrosophenol, and oxidize it to nitrophenol.

However, I could not find this method in any other standard organic chemistry textbook (eg. the book by Clausen, or by Solomons and Fryhle).

Is there any book where this particular reaction is illustrated in details?
