Novel diphenyl ether compounds of the general formula: ##STR1## wherein X represents a hydrogen atom or a nitro group, process for preparing the same and diphenyl ethers of the general formula: ##STR2## wherein R represents a hydrogen atom, or substituted or unsubstituted alkyl group, alkenyl group or alkynyl group, and Y represents an oxygen atom, a sulfur atom, or the group ##STR3## wherein R' is defined as R above, by reacting 2-chloro-4-trifluoromethylphenyl-3,4-dinitrophenyl ether with a compound of the general formula: RYH (III) wherein R and Y have the same meanings as defined above, respectively. The latter diphenyl ether compounds of the general formula (II) are useful as herbicides.
新型二苯醚化合物的一般公式为:其中X代表氢原子或硝基团,制备这些化合物的方法以及一般公式为的二苯醚:其中R代表氢原子,或取代或未取代的烷基,烯基或炔基,Y代表氧原子,硫原子或基团,通过将2-氯-4-三氟甲基苯基-3,4-二硝基苯基醚与一般公式为的化合物反应得到,其中R和Y分别具有与上述定义相同的含义。后一种二苯醚化合物的一般公式(II)可用作除草剂。
