摘要

Imidazole compounds represented by general formula I: wherein: R1 represents a cyano group or a -CSNHR5 group, wherein R5 represents a hydrogen atom, a C1-4 alkyl group, or a -COR6 group, wherein R6 represents a C1-4 alkyl group, a halogenated C1-4 alkyl group, or a phenyl group; R2 and R3 each represents a hydrogen atom; a halogen atom; a nitro group; a cyano group; a trimethylsilyl group; a C3-6 cycloalkyl group; a naphthyl group; an optionally substituted C1-12 alkyl, C2-10 alkenyl, C1-6 alkoxy, phenyl, furyl, thionyl or pyridyl group; an-SOnR7 group, wherein R7 represents a C1-6 alkyl, C2-6 alkenyl , benzyl, an optionally substituted phenyl or pyridyl group; an - NR8R9 group, group, wherein R8 and R9 each represents a C1-4 alkyl group, and n is 0, 1, or 2; or a -CO(NH)mR10 gorup, wherein R10 represents an optionally substituted C1-4 alkyl, C1-4 alkoxy or phenyl group and m is 0 or 1; and R4 represents a C1-6 alkyl group which is optionally substituted with one or more halogen atoms; a C3-6 cycloalkyl group; a phenyl group; a thienyl group; or an -NR11R12 group, wherein R11 and R12 each represents a hydrogen atom, a C1-4 alkyl group which is optionally substituted with one or more halogen atoms, a C2-4 alkenyl group, or R11 and R12 are combined with each other together with a nitrogen atom adjacent thereto to form a pyrrolidinyl group, a piperidinyl group, a morpholino group, or a thiomorpholino group, provided that R11 and R12 are not simultaneously a hydrogen atom; provided that R2 and R3 are not simultaneously a halogen atom. The compounds are effective as biocides.
