Abstract

Ester derivatives of carboxylic acid. Typically I is shown as follows (chemical formula) where R1 is an alkyl group containing 1 to 4 carbon atoms of a straight-chain or branched type; And R2 is the moo, represented by the general formula II, III or IV as follows; (Chemical formula) where R3 is a hydrogen atom or methyl group; X is the oxygen atom or methylene group; R4 is the hydrogen atom or ethyl group; R5 and R6 are identical or different, selected from the group containing Atomic hydrogen , Fluorine atoms, chlorine atoms or methyl groups; R7 is a hydrogen atom or trifluoromethyl group; R8 is selected from a group containing Propagill group, methoxy methyl group Or methylthio; Or methylthio; Or R7 and R8 may be combined to form Melene dioxy chain; And processes associated with the production of this substance, and pesticides and insecticides containing This substance is an active ingredient. Compounds expressed by the general formula I are the beneficial components of Insecticides and insect repellants available today, that is, compounds that have both properties Its fast action and lethal effect, and moreover, provides high safety against Mammals; And in addition, insecticides and insect repellants that contain The above compounds have a lot of practical uses.
