Versuchsvorschrift

Cupric chloride (0.673 g, 2.5 equivalents) was added in one portion to a solution of 3-(2,6-dichloro-4-trifluoromethylphenylhydrazino)propionitrile (0591 g, 2 mmol) in chlorobenzene, and the mixture heated at 65° C. for 50 minutes. The reaction was judged to be complete and was cooled, washed (water), dried (magnesium sulphate), evaporated and separated by chromatography on silica gel to give 3-(2,6-dichloro-4-trifluoromethylphenylhydrazono)propionitrile,
