Abstract
NEW MATERIAL:The titled compound expressed by the formula (R is lower alkyl, halogen-substituted alkyl, alkylamino, etc.).
EXAMPLE: 2 -Chloro- 4 -trifluoromethylphenyl 3 -methylsulfonyloxy- 4 -chlorophenyl ether.
USE: A herbicide, harmless to rice plants even in a large application amount thereof, and extremely effective against scirpus juncoides Roxb. or cyperus serotinus Rottb. The effect is not reduced even in a reducing soil treated with raw rice straws, and in addition may be applied for a longer time in a wider range.
PROCESS: 2-Chloro-5-(2-chloro-4-trifluoromethylphenoxy)phenol is reacted with a compound expressed by the formula X-SO2-R (X is halogen) in an inert solvent, e.g. benzene or toluene, at -20W150°C, prossibly in the presence of an acid binder, e.g. caustic potash or pyridine, to give the compound of the formula.
