A benzimidazole derivative having the formula,
wherein R is cyano or thiocarbamoyl; Q is lower alkyl or a group represented by the formula NQ¹Q², in which Q¹ and Q² are independently lower alkyl, lower alkyl substituted with phenyl, lower alkenyl or lower alkynyl, or they form a lower alkylene ring when taken together at their ends which ring may include a hetero atom; X is hydrogen or halogen; and Z is a group which consists of (a) one oxygen atom or two non-adjacent oxygen atom, (b) -CF₂- group and (c) any one of a single bond, -CF₂-, -CFH-, CFCl- and -CH₂- groups and forms a five-membered or six membered ring together with two adjacent carbon atoms of the benzene ring; is obtained by reacting a corresponding 2-cyanobenzimidazole compound and a sulfamoyl chloride derivative. The benzimidazole derivative is incorporated into agricultural and horticultural fungicides as an active ingredient.
具有以下式子的苯并咪唑衍生物
其中 R 是氰基或硫代氨基甲酰基;Q 是低级烷基或由式 NQ¹Q² 所代表的基团,其中 Q¹ 和 Q² 独立地是低级烷基、被苯基取代的低级烷基、低级烯基或低级炔基,或者当它们在两端结合在一起时形成一个低级亚烷基环,该环可包括一个杂原子;X 是氢或卤素;和 Z 是由(a)一个氧原子或两个不相邻的氧原子、(b)-CF₂- 基团和(c)单键、-CF₂-、-CFH-、CFCl- 和-CH₂- 基团中的任意一个组成的基团,并与苯环的两个相邻碳原子一起形成五元环或六元环。苯并咪唑衍生物可作为活性成分加入农用和园艺杀菌剂中。
