New sulphur-containing derivatives of 5,6-dihydro-2-methyl-4-[3-(trifluoromethyl)phenyl]-2H-1,2,4-oxadiazin- 3(4H)-one, process for their preparation and the intermediates in this process, their application as herbicides and the compositions containing them

摘要

The invention relates to the products of formula (I): <IMAGE> in which n is equal to 0, 1 or 2 and R represents a substituted or unsubstituted, saturated or unsaturated, cyclic or acyclic hydrocarbon radical containing from 1 to 14 carbon atoms, it being understood that when n is equal to 0, R cannot represent an unsubstituted, saturated, acyclic hydrocarbon radical containing from 1 to 4 carbon atoms, to the process for their preparation and to their use as herbicides.
