| titleOfInvention | Improved process for producing phenyl-carbamate derivatives |
| abstract | Herbicidally active substituted phenyl carbamatesn in which R' represents a C 1 -C 6 alkyl group, a C 3 -C 8 cycloalkyl group or an aryl group, which aryl group may be substituted by a halogen atom and/or a C 1 -C 6 alkyl group and/or a trifluoromethyl group, and R 2 represents a C 1 -C 6 alkyl, C 2 -C 6 alkenyl or C 2 -C 6 alkynyl group that may be substituted by a terminal halogen atom, are prepared by reacting N-hydroxyphenyl carbamates IIn with either isocyanates R'-N=C=O or amino acid chlorides R'-NH-COCI in an aqueous medium thus avoiding the use of organic solvents. The end product I may be extracted from the aqueous slurry into a water-immiscible solvent. n The N-hydroxyphenyl carbamates II can be prepared by reacting 3-aminophenol with chloroformates in an aqueous medium, and the resulting product may be reacted in situ, without isolation, with isocyanates, in the same reaction vessel. n Stabilized herbicidal compositions containing compounds I may be prepared by suspending the compounds I in a liquid phase comprising one or more oily components and one or more surfactants. |
