3-HALOALKOXY-4-NITRO-2'-CHLORO-4'-TRIFLUOROMETHYL-DIPHENYL ESTERS, PROCESS FOR THEIR PREPARATION, MEDIUM CONTAINING THEM AND THEIR USE AS HERBICIDES

摘要

The invention relates to novel 3-haloalkoxy-4-nitro-2'-chloro-4'-trifluoromethyl-diphenyl ethers with herbicidal properties. These compounds have good selectivity in different crops of useful plants, e.g. cereals, rice, cotton and, in particular, soybeans and maize. The novel compounds have the formula I (I) wherein R is difluoromethyl or 2-chloro-1,1,2-trifluoroethyl.
