Abstract
本发明涉及一种结构式(Ⅰ)的化合物或其盐,
其中R1是C1-6烷基,R2是卤原子、C1-6烷基磺酰基等,R3和R4各自独立为C1-6烷基或C1-6卤代烷基,R是氢或C1-6烷基。含有结构式(Ⅰ)的化合物的组合物可用作选择胜除草剂来用于玉米和小麦田中的杂草防治。
Description
发明领域
本发明涉及在吡唑环的4位上被苯甲酰基取代的新的吡唑衍生物和除草剂。
背景技术
另一方面,在WO96/26206公报中,公开了一种有结构式[III]的化合物。
发明公开
本发明的目的是提供一种可有利于工业规模合成的除草剂,它能在更低剂量下有效,并且非常安全,其除草活性在杂草和作物间有较高的选择性。
本发明涉及一种除草剂,它含有4-苯甲酰基吡唑化合物作为活性组分,该化合物结构上的特征是用通式[I]表示的苯甲酰基部分的3位用被一个杂环取代,2位的取代基是C1-6烷基。
就是说,本发明涉及一种结构式[I]的化合物或其盐,以及含有这种化合物或这种盐的除草组合物:其中R1是C1-6烷基,R2是卤原子、C1-6烷硫基和C1-6烷基亚磺酰基或C1-6烷基磺酰基,R3和R4各自独立为氢、C1-6烷基或C1-6卤代烷基,R是氢原子或C1-6烷基。
现在,将在下文详细描述本发明。
R2是卤原子,如氟、氯和溴;C1-6烷硫基,如甲硫基、乙硫基、丙硫基和异丙硫基;C1-6烷基亚磺酰基,如甲基亚磺酰基、乙基亚磺酰基、丙基亚磺酰基和异丙基亚磺酰基;或是C1-6烷磺酰基,如甲磺酰基、乙磺酰基、丙磺酰基和异丙磺酰基。
R3和R4各自独立为氢、C1-6烷基(如甲基、乙基、丙基、异丙基、丁基和叔丁基)、或C1-6-卤代烷基(如三氟甲基和三氟乙基)。
R是氢原子或C1-6烷基(如甲基、乙基、丙基、异丙基、丁基、异丁基和叔丁基)。
化合物的制备
在上述方法中,结构式[IVa]和[IVb]的化合物可分别通过1摩尔结构式[VII]的化合物与1摩尔结构式[Va]的化合物在1摩尔或过量的碱存在下反应制得,其中Q如上所述,其前提条件是结构式[VII]化合物或结构式[Va]化合物中的任何一个过量。
可用于上述反应中的碱的实例是碱金属氢氧化物(如KOH和NaOH)、碱金属碳酸盐(如碳酸钠和碳酸钾)、碱土金属氢氧化物(如氢氧化钙和氢氧化镁)、碱土金属碳酸盐(如碳酸钙)、三(C1-6烷基)胺(如三乙胺和二异丙基乙胺)、有机碱(如吡啶)和磷酸钠等。
而且,可用于上述反应的溶剂实例是水、二氯甲烷、氯仿、甲苯、乙酸乙酯、二甲基甲酰胺(DMF)、四氢呋喃(THF)、二甲氧基乙烷(DMB)、乙腈等。

另外,本发明的除草剂可与任何已知的杀菌剂、杀虫剂、杀螨剂、其它除草剂、植物生长调节剂和肥料混用。特别是,当本发明的除草剂与其它除草剂混合时,本发明的除草剂的量可以减少。另外,采用本发明的除草剂可减少劳动力,预计本发明混合制剂的增效效果可有更高的效果。在这种情况下,也可以使本发明的除草剂与多种已知的除草剂合用。
适于与本发明除草剂混合的制剂实例包括含有N-酰苯胺的除草剂(如吡氟草胺和敌稗)、含有氯代N-乙酰苯胺除草剂(如甲草胺和丙草胺)、含有芳氧基链烷酸的除草剂(如2,4-D和2,4-DB)、含有芳氧基苯氧基链烷酸的除草剂(如禾草灵-甲基和噻唑禾草录-乙基)、含有芳基羧酸的除草剂(如麦草畏和pyrithiobac-sodium)、含有咪唑啉酮的除草剂(如灭草喹和咪草烟)、含有脲的除草剂(如敌草隆和异丙隆)、含有氨基甲酸酯的除草剂(如氯苯胺灵和苯敌草)、含有硫代氨基甲酸酯的除草剂(杀草丹和扑草灭)、含有二硝基苯胺的除草剂(如氟乐灵和二甲戊乐灵)、含有二苯基醚的除草剂(如三氟羧草醚-钠和氟黄胺草醚)、含有磺酰脲的除草剂(如苄嘧黄隆-甲基和烟嘧黄隆)、含有三嗪酮(triazinone)的除草剂(如嗪草酮和苯嗪草酮)、含有三嗪的除草剂(如莠去津和eyanazine)、含有三唑嘧啶的除草剂(如flumetsulam)、含有腈的除草剂(如溴苯腈和敌草腈)、含有哒嗪酮的除草剂(如杀草敏和达草灰)、含有磷酸的除草剂(如草甘膦和草胺膦)、含有季铵盐的除草剂(如对草快和双苯唑快)、环状亚胺的除草剂(如flumiclorac-pentyl和fluthiacet-methyl)、其它除草剂(如isoxaben、乙呋草黄、恶草灵、二氯喹啉酸、异噁草酮、sulcotrione、环庚草醚、氟硫草定、吡唑特、哒草特、胺草唑、噻草平、呋草黄)、和含有环己二酮的除草剂(如稀禾定和肟草酮)。而且,在这些活性组分的组合中可加入植物油或油的浓缩物。
实施例
[除草剂]
现在将在下文中描述本发明的一些除草剂组合物的配方实例,然而,活性组分化合物、添加剂和加料比不应局限于这些实施例描述的范围内,它们可在较广的范围内改变或扩大。在配方实施例中,“份”指“重量份数”。
(实施例2)可湿性粉剂本发明化合物 20份白炭 20份硅藻土 52份烷基硫酸钠 8份
均匀混合这些材料,然后细磨获得含有20%有效组分的可湿性粉剂。
(实施例3)可乳化浓缩剂本发明化合物 20份二甲苯 55份二甲基甲酰胺 15份聚氧乙烯苯基醚 10份
均匀混合这些材料并溶解,获得含有20%有效组分的乳剂。
(实施例4)颗粒剂本发明化合物 5份滑 40份粘土 38份膨润土 10份烷基硫酸钠 7份
均匀混合这些材料,细磨、造粒,获得直径为0.5-1.0mm、含有5%有效组分的颗粒。
[试验实施例]
现在下文将描述关于本发明除草效果的试验实施例。
根据下列评价标准来评价除草效果,它表示的每一指标表示除草组合物的强度。
评价标准:杀死的杂草% 除草指标0% 020-29% 240-49% 460-69% 680-89% 8100% 10
另外,数值1、3、5、7、9分别表示在0和2、2和4、4和6、6和8、以及8和10之间的数值。(测试实施例1)叶面施用生长在高地作物田中的杂草在大小为200cm2的盆中填入土壤,将绒状叶(Velvet leaf)、藜、苍耳、看麦娘和玉米的种子分别种入盆中。在用土壤覆盖种子后,使种子在温室内生长。当各植物长至高度为5-25厘米时,将实施例3中所述的含有样品化合物的乳剂的稀释水溶液用小的喷嘴喷洒在杂草的茎和叶子上,使得每个盆内每种活性组分的施用量为250克/公顷。3周后,检查各化合物对杂草的除草效果,结果显示在表2中。
试验表明,本发明的化合物表明了对各种杂草有卓越的除草活性,特别对玉米植物有较高的选择性,不会对其产生有害影响。
