This is an orgo. theory question:
If I have a benzene ring with NH2 attached and want to replace this with COOH:
_ _
/ \_NH2 --> / \_COOH
\_/ \_/
I believe that the text book way to do this is to convert the molecule to a disulfide salt with NaNO2 and HCl, then use Cupric Cyanide / Potassium CN to change it into a benzen ring with a CN on it. Then it can be reacted in an acidic aqueous solution to get the desired molecule.
First off, is this correct? Secondly, is there another route that can be used?
No, I am not a college orgo student, that needs help on his homework. I am an ignorant man trying to teach myself some chemistry.
