<p>Ring-substituted N-(2,2-difluorcalkanoyl)-o-phenylenediamine compounds are described herein. These compounds are useful as herbicides, insecticides, parasiticides, anthelmintic and nematocidal agents. The ophenylenediamine compounds are prepared by acylation of the corresponding diamine to introduce the 2,2-difluoro-alkanoyl group.</p> |
