Abstract
Herbicidal 3- and/or 5-halogenomethyl-pyrid-2-yloxyphenoxy compounds and processes for making and using the same. Intermediates for making these compounds and their preparation are also disclosed. Thus, for example, 2-chloro-5-trichloromethylpyridine is prepared by a liquid phase chlorination of 3-methylpyridine under the influence of ultra violet light.
