Agricultural chemicals and agents for preventing the attachment of aquatic organisms containing one or more such ethylene derivatives.

Description: Technical Field The present invention relates to novel ethylene derivatives, and also to agricultural chemicals and agents for preventing the attachment of aquatic organisms containing said derivatives as an active ingredient. The agricultural chemicals as referred to herein include insecticides, acaricides, nematocides, herbicides and fungicides, etc., and are especially pesticides in the field of agriculture, horticulture, stock farming and sanitation. The agent for preventing the attachment of aquatic organisms are chemicals for preventing the attachment of harmful aquatic organisms such as shells and algae to fishing nets, the bottoms of ships, marine equipment such as buoys, marine constructions, circulating water systems in thermal and atomic power plants, inlet channels for heat exchanger cooling water in chemical industry, underwater constructions and reservoirs. Background Art For acrylonitrile derivatives, Japanese Patent Application Laid-Open No. Sho 53-92769 discloses the use of 2'-chloro-3-hydroxy-2-(4-phenyl-2-thiazolyl)-cinnamoyl nitrile as an insecticide; and International Patent Application Laid-Open No. WO-95/29591 discloses its use as an aquatic adhesion inhibitor. Japanese Patent Application Laid-open No. Sho 60-11452 discloses the use of 2-(4-chlorophenyl)-3-(3-pyridyl)-3-oxopropionitrile as a herbicide and Japanese Patent Application Laid-open No. Sho 60-11401 discloses its use as a fungicide. With the long-term use of insecticides and fungicides, recently, some pests have become resistant to chemicals and are often difficult to exterminate with conventional insecticides and fungicides. In addition, some insecticides are highly toxic and are prone to remain long, without being decomposed, to destroy the ecosystem. Accordingly, it is always expected to develop novel, low-toxic and low-persistent insecticides and fungicides. On the other hand, in order to prevent the adhesion and growth of marine and freshwater aquatics, it is used antifouling coatings comprising organic tin compounds such as bis(tributyltin) oxide or copper compounds such as copper sulfate and cuprous oxide. However, organic tin compounds are highly toxic, though being effective in preventing the adhesion of aquatics, and are especially prone to accumulate in the bodies of fishes and shellfishes. As so promoting the environmental pollution, the use of those compounds is now under legal controls. Copper compounds are widely used in antifouling coatings for inlet channels and for the bottoms of ships. However, like tin compounds, copper compounds contain a copper as a heavy metal. Therefore, the use of copper compounds will bring about the environmental pollution in future, and agents for preventing the attachment of aquatic organisms comprising such copper compounds are not preferred. Under the above-mentioned situation, it has been desired agents for preventing the attachment of aquatic organisms that have few influences on the ecosystem and bring about little secondary pollution.

Method A in (Scheme 1) is to react an acetonitrile derivative of formula (3) with an acid chloride, ester or amide of formula (4) or with an acid anhydride of formula (5) to give compounds (1') of the present invention. The compound (1') of the invention is optionally reacted with an alkyl halide, an alkyl sulfonate, a trimethylsilyl halide, a sulfonyl chloride, a sulfamoyl chloride, a thiocarbamoyl chloride, an acid chloride or an ester of formula (8) to be converted into compounds (1) of the invention. Depending on the type of B in the compounds (1) of the invention, the compound (1') is reacted with a dihydropyran, an isocyanate or a thioisocyanate to give the compounds (1). In Method A, if the compound of formula (4) or (5) is used in an excessive amount, the compounds (1) can be directly obtained without isolating the compounds (1'). Where Q is bonded to the acrylonitrile moiety via a nitrogen atom, compounds (1') may be produced according to Method B.

Where A is bonded to the acrylonitrile moiety via a nitrogen atom, compounds (1') may be produced according to Method C. Method C is to react a cyanoacetic acid derivative of formula (9) with a heterocyclic compound of formula (10) to give compounds (1') of the invention. As the case may be, the compound of formula (9) will be prepared by reacting an acetonitrile derivative of formula (3), such as that used in Method A, with a carbonic acid ester in the presence of a base. As the case may be, the processes of (Scheme 1) are preferably effected in the presence of a base. The base to be used includes, for example, alkali metal alkoxides such as sodium ethoxide, sodium methoxide and t-butoxy potassium; alkali metal hydroxides such as sodium hydroxide and potassium hydroxide; alkali metal carbonates such as sodium carbonate and potassium carbonate; organic bases such as triethylamine, pyridine and DBU; organic lithium compounds such as butyl lithium; lithium amides such as lithium diisopropylamide and lithium bistrimethylsilylamide; and sodium hydride.

The reaction temperature may be freely settled within a range between -30 °C and 200 °C. Preferably, the reaction temperature falls between 0 °C and 150 °C, or between 0 °C and the boiling point of the solvent if used.

Alternatively, a phenylacetic acid derivative or a heterocyclic acetic acid derivative is converted into the corresponding amide derivative, which is then dehydrated to give compounds (3). 2) A heterocyclic halide (15) is condensed with a cyanoacetate (16) in the presence of a base to give a compound (17), which is then hydrolyzed and decarboxylated to give compounds (3). 3) To obtain compounds (3) where Q is bonded to the ethylene moiety via a nitrogen atom, a heterocyclic derivative (6) where the nitrogen atom of Q is unsubstituted is reacted with a haloacetonitrile derivative in the presence of a base. Alternatively, the compound (6) is reacted with a compound (18) in the presence of a base to give a compound (17), said compound (18) being obtained through halogenation of a cyanoacetate, and thereafter the compound (17) is hydrolyzed and decarboxylated to obtain the compounds (3). The compounds (7) to be used in (Scheme 1) can be produced by condensing a benzoic acid halide or heterocyclic carboxylic acid halide with a cyanoacetate in the presence of a base followed by halogenating the resulting condensate. The above-mentioned halomethyl-heterocyclic compounds, alkylsulfonyloxymethyl-heterocyclic compounds and arylsulfonyloxymethyl-heterocyclic compounds can be derived from heterocyclic methane derivatives or heterocyclic carboxylate derivatives that are produced according to ordinary methods (see Alan R. Katritzky, and Charles W. Rees; Comprehensive Heterocyclic Chemistry, Vol. 2, Vol. 3, Vol. 4, Vol. 5 or Vol. 6).

Industrial Applicability With the long-term use of insecticides and microbicides, recently, some pests have become resistant to chemicals and are often difficult to exterminate with conventional insecticides and microbicides. In addition, some insecticides are highly toxic and are prone to remain long, without being decomposed, to destroy the ecosystem. Accordingly, the present invention provides novel, non-toxic and non-persistent insecticides and fungicides, and provides agents for preventing the attachment of aquatic organisms having few influences on the ecosystem and causing little secondary pollution.
