Yeah, that's where ning got the idea...
As for refs??!! come on, rhodium's page and a standard O-chem textbook, guys! None of this is earth shatteringly new or exotic stuff! You want a ref for nitration of substituted bezene? really? Then ning will have to go find one, obviously. The reduction of nitro to amino is also std, Zn or Fe in HCl. No papers, just an old O-chem book.
Oxidation of aniline to quinone is nothing new, and ning has seen similar reactions with a beilstein search. MnO2 in H2SO4. Not much more is known by ning. Ning is asking for criticism of idea because ning is not a chem expert. If ning had all the papers, there would be little to ask. In fact, ning doesn't know why Sr. L assumes ning has a secret stash of world-shaking scientific literature that ning refuses to release. Ning doesn't. Ning has some papers ning will type as soon as the demands of PHYSICAL REALITY permit. Ning has only the best wishes for the hive, and works hard to further the knowledge and shared power of the hive. Ning promises not to be stingy, and asks the same from you, Sr. L.
