Question

How will you carry out the following conversions?
(i) toluene $\to$ p-toluidine
(ii) p-toluidine diazonium chloride $\to$ p-toluic acid.

Answer 1

$\left(i\right)$ Toulene $\to$ P-toluidine.

Toulene in presence of methanol over heated catalyst bed of $Zsr-5$ Zeolite gives p-toluidine or paraxylene.

$\left(ii\right)$ p-toluidine diazonium chloride $\to$ p-toulic acid.

Refer IMAGE $02$

p-toulidine diazonium chloride on reaction $CuCN$ and $kCN$ gives substituted nitrile. Nitrile which on hydrolysis gives touldic acid.
