SYNTHESIS OF TETRACHLOROPHTHALONITRILE BY OXIDATIVE AMMONOLYSIS OF TETRACHLORO-o-XYLENE
The production of tetrachlorophthalonitrile by oxidative ammonolysis of tetrachloro-o-xylene is described.The chlorine atoms in the ring affect the mechanism of the transformation of the alkyl groups into nitrile groups, and the latter are therefore formed independently. Tetrachloro-o-tolunitrile and tetrachlorophthalimide are side products of the reaction.

FORMATION OF AROMATIC NITRILES BY DIRECT REPLACEMENT OF THE NITRO GROUPS OF DINITROTETRACHLOROBENZENES
Direct replacement of nitro by cyano groups has been effected by treatment of the dinitrotetrachlorobenzenes in refluxing chloroform with aqueous cyanide ion in the presence of a phase transfer catalyst.
