ABSTRACT:
2,3,5,6-Tetrachloropyridine and/or 3,5,6-trichloropyridin-2-ol can be obtained, using a simple novel process, by reacting trichloroacetyl chloride, in the presence of a catalyst, for example copper (I) chloride or -bromide, with acrylonitrile. 2,3,5,6-Tetrachloropyridine and 3,5,6-trichloropyridin-2-ol are suitable for producing various active substances, particularly for producing insecticides, herbicides and fungicides.
