1,265,856. Chlorinated nitriles. DIAMOND SHAMROCK CORP. 21 Nov., 1969 [22 Nov., 1968], No. 57201/69. Heading C2C. Chlorinated aromatic or heteroaromatic nitriles are prepared by ammoxidating a precursor compound in the presence of ammonia and a source of oxygen and reacting the uncondensed gaseous ammoxidation product with chlorine at a sufficient temperature to produce a chlorinated nitrile. The precursor may be an alkylated or alkarylated benzene, naphthalene, pyridine, pyrazine, pyrimidine or triazine compound which may be halogen substituted. The invention further comprises trichloro-2-cyanopyrazine, heptachloro-2-naphthonitrile, heptachloro- 1-naphthonitrile and octachloro-4,4<SP>1</SP>-biphenyldicarbonitrile The novel compounds may be used in pesticidal compositions. |
