A process for producing 1-substituted-2-cyanoimidazole compounds is described, which comprises (1) undergoing a reaction of a compound represented by formula (IV), hydroxylamine or a mineral acid salt thereof, and glyoxal or glyoxime to produce a compound represented by formula (III), (2) undergoing a reaction of the compound represented by formula (III) with thionyl chloride or thionyl bromide in the presence of N,N-dialkylamide to produce a reaction mixture, and then reacting the produced reaction mixture with sulfur chloride to produce a 2-cyanoimidazole compound represented by formula (II), and (3) undergoing a sulfamoylation reaction and an isomerization reaction of the 2-cyanoimidazole compound represented by formula (II) and a compound represented by formula (V) in the presence of at least one base selected from carbonates of alkali metals and bicarbonates of alkali metals and a polar solvent to produce a 1-substituted-2-cyanoimidazole compound represented by formula (I-b). The formulae and substituents formulae are specifically defined in the specification. ##STR1##

N-Pyridyltoluidine-containing fungicidal water dispersible granules

An aminocarbonyl-substituted pyridinesulfinic acid intermediate for production of an herbicide having formula (V): ##STR1## wherein R.sub.3 and R.sub.4 are selected from the group consisting of hydrogen and alkyl groups, or a salt thereof. The aminocarbonyl-substituted pyridinesulfinic acid or salt thereof is useful as the precursor of aminosulfonyl-substituted pyridinecarbonic acid amide, which in turn is useful as the starting material for agricultural chemicals, medicine, etc.

Mercapto-substituted pyridine compounds, aminocarbonyl-substituted

A process for preparing a S-substituted phosphorochloridothiolate having the formula: ##STR1## wherein R.sup.1 is a chlorine atom or an alkoxy or phenoxy group which may be substituted, and R.sup.2 is an alkyl, alkenyl, alkynyl, cycloalkyl or phenyl group which may be substituted, which comprises isomerizing an O-substituted phosphorochloridothionate having the formula: ##STR2## wherein R.sup.1 and R.sup.2 are as defined above, in the presence of a Lewis acid catalyst or a phosphorus compound catalyst.

Process for preparing a s-substituted phosphoro-chloridothiolate

A novel amino-trifluoromethylpyridine compound selected from the group consisting of 3-amino-5-trifluoromethylpyridine, 2-amino-4-trifluoromethylpyridine, and 2-amino-4,6-bis(trifluoromethyl)pyridine, and, a process for preparing the same by reacting a halogeno-trifluoromethylpyridine compound with ammonia at a temperature of 50.degree. to 200.degree. C. The compound is useful as an intermediate from which a compound effective in controlling various harmful organisms or an effective component compound of medicines can be easily derived.
