摘要:
An N-benzoyl urea compound having the formula: wherein X is a hydrogen atom, a halogen atom or a nitro group, n is an integer of from 1 to 3, and Q is wherein Y, is an unsubstituted or substituted alkyl group, or an alkoxy or alkoxycarbonyl group with its alkyl moiety unsubstituted or substituted, Y 2 is a hydrogen atom, a halogen atom, a nitro group, an unsubstituted or substituted alkyl group, or an alkoxy or alkoxycarbonyl group with its alkyl moiety unsubstituted or substituted, Z is a hydrogen atom, a halogen atom, a trifluoromethyl group or a nitro group, and each of A and B is =CH- or a nitrogen atom, provided that one of A and B is =CH- and the other is a nitrogen atom, with the provisos (1) that when Q is where when X is a hydrogen atom and Y, is an alkyl group, Z is not a hydrogen atom, a halogen atom nor a trifluoromethyl group, and (2) that when Q is wherein A is a nitrogen atom and Y, is a trifluoromethyl group, Y 2 is other than a hydrogen atom.
摘要:
An O-(N-alkoxy-pyridinecarboximidoyl)-phosphate is represented by the following formula: wherein X is a halogen atom, a lower alkyl group, a lower acyloxy group. a trifluoromethyl group or a nitro group; Y is an oxygen atom or a sulfur atom; R is a lower alkyl group; n is an integer of 0 to 3; and Z 1 and Z 2 are each a lower alkoxy group, a lower alkylthio group, a phenyl group which may be substituted by a lower alkyl group, a phenoxy group, a haloalkoxy group or a lower alkylamino group. The compound of formula (I) is useful as an active ingredient of insecticides or acaricides and is produced by reacting an N-alkoxy-pyridinecarboximidic acid having the formula (A): wherein X, R and n are as defined above with a phosphoric halide having the formula (B): wherein Hal is a halogen atom and Y, Z, and Z. are as defined above in the presence of an alkaline material.
