&agr;-unsaturated amines, their production and use

The present invention provides a novel triazine derivative of the formula

Triazine derivative, production and use thereof

.alpha.-Unsaturated amines of the formula: ##STR1## wherein X.sup.1 and X.sup.2 are such that one is an electron-attracting group with the other being a hydrogen atom or an electron-attracting group; R.sup.1 is a group attached through a nitrogen atom; R.sup.2 is a hydrogen atom or a group attached through a carbon, nitrogen or oxygen atom; n is an integer equal to 0, 1 or 2; A is a heterocyclic group or a cyclic hydrocarbon group, and salts thereof and their agrochemical use as insecticidal and/or miticidal agents are described.

.alpha.-unsaturated amines, their production and use

The present invention provides a novel triazine derivative of the formula ##STR1## wherein ring A is an optionally substituted aromatic group; X is an oxygen or sulfur atom;

1, 2, 4-Triazin-3-one derivatives, production and use thereof

The present invention relates to compounds represented by the formula: ##STR1## wherein R.sup.1 is (1) an optionally substituted alkyl group which may be bonded through a hetero atom, (2) an optionally substituted acyl group, (3) an alkylsulfonyl group, (4) an alkylsulfinyl group, or (5) an optionally substituted sulfamoyl group; A is --N.dbd. or -CH.dbd.; R.sup.2 is a hydrogen atom or an alkyl group which may optionally be substituted with halogen and which may be bonded through a hetero atom;

1,2,4-triazine-3, 5-dione derivatives, their production and use thereof

An insecticidal composition containing a guanidine derivative of the formula: ##STR1## wherein R.sup.1 is an optionally substituted homocyclic or heterocyclic group, n is 0 or 1, R.sup.2 is a hydrogen atom or an optionally substituted hydrocarbon group, R.sup.3 is a primary, secondary or tertiary amino group, X is an electron attractive group such as nitro or trifluoroacetyl group, provided that when n is 0, R.sup.1 is an optionally substituted heterocyclic group or a salt thereof.

Guanidine derivatives, their production and insecticides

Halogen substituted 5-thiazole methane amine compounds

Alpha-unsaturated amine pyridine compounds

A 4-pyrazolyl phosphorous acid ester of the following formula, ##STR1## (R is a lower alkyl group; Y is a phenyl group which may optionally be substituted by a halogen, halogens, a lower alkyl group or a halogen and a lower alkyl group.) which is produced by reacting corresponding 4-hydroxylpyrazole compound with a trialkyl phosphite. The ester gives 4-pyrazolyl phosphorothioate by the reaction with an alkylsulfenyl halide.
