A 2-fluoroethoxy-substituted benzene derivative represented by the general formula ##STR1## wherein X represents an oxygen or sulfur atom, R.sup.1 and R.sup.2 represent a hydrogen atom or a lower alkyl group, n represents 0 or 1, and A represents a group of the general formula ##STR2## in which R.sup.3 and R.sup.4 represent a hydrogen atom, a halogen atom, a lower alkyl group, a lower alkoxy group, a lower alkylthio group, a lower haloalkyl group, a lower haloalkylthio group or a methylenedioxy group, R.sup.5 and R.sup.6 represent a hydrogen atom or a lower alkyl group, and p and m represent 0 or 1. This compound is useful as an active ingredient of insecticidal and acaricidal agents, and can be produced by reacting a compound of the general formula ##STR3## with a compound of the general formula A--D (IV) wherein in general formulae (III) and (IV), A, R.sup.1, R.sup.2 and n are as defined above, and one of B and D represents a a halogen atom and the other represents a group of the general formula --X--M in which X is as defined above, and M represents a hydrogen atom or an alkali metal atom or an alkaline earth metal atom, provided that when n is 0, B is the group --X--M and D is a halogen atom.
一种2-氟乙氧基取代的苯衍生物,由通式##STR1## 表示,其中X代表氧或硫原子,R1和R2代表氢原子或低碳基,n代表0或1,A代表通式##STR2## 中的一种基团,其中R3和R4代表氢原子、卤素原子、低碳基、低烷氧基、低烷硫基、低卤烷基、低卤烷硫基或亚甲二氧基基团,R5和R6代表氢原子或低碳基,p和m代表0或1。该化合物可用作杀虫剂和杀螨剂的活性成分,并可通过将通式##STR3## 的化合物与通式A-D(IV)的化合物反应而制得,其中在通式(III)和(IV)中,A、R1、R2和n的定义如上所述,B和D中的一个代表卤素原子,另一个代表通式--X--M的基团,在该基团中,X如上所述,M代表氢原子或碱金属原子或碱土金属原子,前提是当n为0时,B是基团--X--M,D是卤素原子。
