Germination-stimulant carbamate derivatives and process for preparation thereof

An ester compound represented by formula (1): wherein Rrepresents hydrogen or methyl, Rrepresents hydrogen or C1-C4 alkyl, and Rrepresents hydrogen or C1-C4 alkyl; has an excellent pest control effect and is therefore useful as an active ingredient of a pest control agent. 

Ester compound and use thereof

An ester compound represented by formula (1): wherein Rrepresents hydrogen, fluorine, C1-C4 alkyl, C1-C4 alkoxy, C1-C4 alkoxymethyl, or C1-C4 alkylthiomethyl; Rrepresents hydrogen or methyl, Rrepresents hydrogen or C1-C4 alkyl, and Rrepresents hydrogen or C1-C4 alkyl; has an excellent pest control effect and is therefore useful as an active ingredient of a pest control agent. 

Pyrethrinoid-type esters as pesticides

An ester compound represented by formula (1): wherein Rrepresents C-Calkyl, has an excellent pest control effect and is therefore useful as an active ingredient of a pest control agent.

Hydantoin derivatives of cyano-substituted chrysanthemic acid esters and their use in pest control

An ester compound represented by formula (1): 

Containing the 1,3-benzodioxol compound represented by the formula (I): together with a pesticidal active ingredient in a pesticidal composition enhances a pest control effect of the pesticidal composition.

1,3-benzodioxol compound and use of same

3-Phenoxy-2-pyridone compound can be produced by making the amide compound of the formula (1): 

Process for production of phenoxy-substituted 2-pyridone compounds

Process of producing cyclopropanecarboxylate compounds

A propynyl compound shown by the formula: ##STR1## wherein R represents a lower alkyl group or a hydrogen atom, is an intermediate for producing 3-Z-(1-propenyl)-2,2-dimethylcyclopropanecarboxylic acid esters advantageously in industry.

Process for producing 3-propynyl-2-2-dimethylcycloprophane-carboxylic

Novel fluorine-containing carboxylic acid compounds of formula (II) are provided that can be reacted together with a base to produce industrially useful 3-(2-chloro-2-fluorovinyl)-2,2-dimethyl cyclopropanecarboxylic acid compounds of formula (I). The fluorine-containing containing carboxylic acid compounds of formula (II), if so desired, can be produced by reacting together a carboxylic acid compound of formula (III) and trichlorofluoromethane. In each of the formulas (I), (II), and (III), R is a lower alkyl group or a hydrogen atom. ##STR1##

Fluorine-containing carboxylic acid compounds, methods for their

A process for the production of a cyclopentenol compound represented by the formula I: ##STR1## wherein R.sub.1 represents a 2-propenyl group or a 2-propynyl group from a cyclopentenolone compound represented by the formula II: ##STR2## by protecting the hydroxyl group of the compound II, reacting the protected compound II with a reagent system obtained from TiCl.sub.4, Zn and CH.sub.2 Br.sub.2 or CH.sub.2 I.sub.2 and removing the protecting group from the resulting reaction product.

Process for the production of a cyclopentenol derivative
