本发明涉及通式(I)的新的N-(4-氟苯基)杂
芳基氧基乙酰胺类化合物(其中R及Het的定义如
说明书中所述)及其制备方法以及它们作为除草剂的
应用。
Description
本发明涉及新的N-(4-氟苯基)杂芳基氧基乙酰胺类化合物、它们的制备方法和它们作为除草剂的应用。
已经公开了某些杂芳基氧基乙酰胺类化合物,例如N-甲基-2-(5-氯-1,3,4-噻二唑-2-基氧基)-N-乙酰苯胺(参见EP-A 192,117),具有除草性能(还参见EP-A 5,501、EP-A 18,497、EP-A 37,524、EP-A 94,541、EP-A 217,496、EP-A 348,735、EP-A 348,736、EP-A 348,737)。
但是,先前已知的杂芳基氧基乙酰胺类化合物的除草活性并不总是令人完全满意的。
现已发现通式(Ⅰ)的新的N-(4-氟苯基)杂芳基氧基乙酰胺类化合物,
其中
R代表甲基或乙基,和
Het代表芳族五元杂环,它选自噁唑基或噻唑基(它们各自都可任意地被卤素、氰基、甲基、乙基、正-或异丙基、正-、异-、仲-或叔丁基、二氟甲基、二氯甲基、三氟甲基或三氯甲基取代)、1,2,4-噁二唑基、1,3,4-噁二唑基、1,2,4-噻二唑基或1,3,4-噻二唑基(它们各自均可任意地被氟、氯、溴、甲基、乙基、正-或异丙基、正-、异-、仲-或叔丁基、三氟甲基、二氯甲基、三氯甲基、一氯二氟甲基、一氟二氯甲基、甲硫基、乙硫基、正-或异丙硫基、甲基亚磺酰基、乙基亚磺酰基、正-或异丙基亚磺酰基、甲磺酰基、乙磺酰基、正-或异丙基磺酰基、苯基或氟苯基取代)、苯并噁唑基或苯并噻唑基(它们各自均可被氯、溴、甲基、乙基、正-或异丙基、二氟甲基、二氯甲基、三氟甲基或三氯甲基取代);以及如果R代表乙基,Het还代表未取代的苯并噁唑基和苯并噻唑基。
另外还发现,当通式(Ⅱ)的杂环化合物与通式(Ⅲ)的N-(4-氟苯基)羟基乙酰胺类化合物反应时,得到了式(Ⅰ)的新化合物,如果必要,反应在有酸性接受体、稀释剂和催化剂存在下进行,
其中Het的意义如上,以及X代表卤素或烷基磺酰基,
其中R的意义如上。
另外,发现通式(Ⅰ)的新的N-(4-氟苯基)杂芳基氧基乙酰胺类化合物具有有意义的除草性能。
令人惊奇的是,本发明的式(Ⅰ)化合物比已知的化学组成类似的化合物N-甲基-2-(5-氯-1,3,4-噻二唑-2-基氧基)-N-乙酰苯胺具有强得多的除杂草活性,同时作物(例如大豆)的耐受性很好。
具体地讲,本发明涉及这样的式(Ⅰ)化合物,其中
R代表甲基或乙基,以及
Het代表1,2,4-噻二唑基(它可任意地被氯、三氟甲基、一氯二氟甲基或甲磺酰基取代)、1,3,4-噻二唑基(它可任意地被氯、三氟甲基、一氯二氟甲基或甲磺酰基取代),或是苯并噁唑基或苯并噻唑基,它们各自均可被氯单取代。
所述基团的上述一般定义,或对优选范围所提及的基团的定义,既适用于式(Ⅰ)的最终产物,又同样适用于每一种情形里制备所需的起始物或中间体。
所述基团的这些定义可以根据需要彼此组合,这就是说,也处在上述的优选化合物的范围之内。
例如,如果使用3,5-二氯-1,2,4-噻二唑和N-(4-氟苯基)-N-甲基羟基乙酰胺作为起始物,则本发明制备方法中的反应过程可以用以下式子表示:
作为起始物使用的通式(Ⅱ)的杂环化合物是已知的,和/或可以用本身已知的方法制备(参见J.Org.Chem.27(1962),2589-2592;EP-A 18,497;EP-A 165,537;EP-A 308,740;EP-A 348,735;EP-A 348,737)。
式(Ⅲ)的N-(4-氟苯基)羟基乙酰胺类化合物再作为起始物使用,它也是已知的,和/或可以用本身已知的方法制备(参见EP-A 37,524;EP-A 348,735;制备实施例)。
本发明用于制备式(Ⅰ)新化合物的方法优选用稀释剂进行。这些稀释剂优选包括烃类,例如甲苯、二甲苯或环己烷;卤代烃类,例如二氯甲烷、氯化乙烯、氯仿或氯苯;醚类,例如乙醚、二丙醚、二异丙醚、二丁醚、二异丁醚、乙二醇二甲醚、四氢呋喃和二噁烷;醇类,例如甲醇、乙醇、丙醇、异丙醇、丁醇、异丁醇、仲丁醇或叔丁醇;酮类,例如丙酮、甲基乙基酮、甲基异丙基酮、甲基异丁基酮;酯类,例如乙酸甲酯和乙酸乙酯;酰胺类,例如二甲基甲酰胺、二甲基乙酰胺和N-甲基吡咯烷酮;腈类,例如乙腈和丙腈;亚砜类,例如二甲基亚砜;以及水或盐的水溶液。
本文中优选使用的盐是碱金属或碱土金属的氯化物或硫酸盐,例如氯化钠、氯化钾或氯化钙。特别优选氯化钠。
本发明方法最好在使用酸结合剂的情况下进行。优选的酸结合剂是强碱性的碱金属和碱土金属化合物,例如氧化物,如氧化钠,氧化钾、氧化镁和氧化钙;氢氧化物,如氢氧化钠、氢氧化钾、氢氧化镁和氢氧化钙;醇化物,例如叔丁醇钠和叔丁醇钾;以及/或碳酸盐,例如碳酸钠、碳酸钾、碳酸镁和碳酸钙。
在某些情形里加入0.01%至10%(重量)(按所用的式(Ⅲ)的2-羟乙酰胺计)的相转移催化剂可能有利。可以提到的这类催化剂的实例有:氯化四丁基铵、溴化四丁基铵、溴化三丁基甲基鏻、氯化三甲基-C13/C15-烷基铵、二苄基二甲基铵甲基硫酸盐、氯化二甲基-C12/C14-烷基苄基铵、氢氧化四丁基铵、18-冠-6、氯化三乙基苄基铵、氯化三甲基苄基铵和溴化四乙基铵。
在进行本发明的方法时,反应温度可以在很大的范围内变化。一般来说,本发明的方法在-50℃至+110℃的温度下进行,优选温度为-20℃至+80℃。
本发明的方法通常在大气压下进行,但是也可以在加压或减压下进行,例如在0.1和10巴之间。
为进行本发明的方法,通常每摩尔式(Ⅱ)的杂环化合物使用0.5到5摩尔、优选0.8至1.5摩尔的式(Ⅲ)的羟基乙酰胺。反应物可以按照所希望的任何顺序组合。在每一种情形里,都将反应混合物搅拌直到反应结束,用惯用方法对产物进行后处理(参见制备实施例)。
本发明的活性化合物可以用作脱叶剂、干燥剂、杀阔叶植物剂,特别是可用作除杂草剂。所谓杂草,从最广泛的意义上来说,应理解为所有的植物,只要它们生长在人们不希望它生长的地方,都可称之为杂草。本发明化合物是作为广谱除草剂还是作为选择性除草剂,这主要取决于所用的量。
本发明的活性化合物可用于杀灭例如以下植物:
以下各属的双子叶杂草:欧白芥属、独行菜属、拉拉藤属、繁缕属、母菊属、春黄菊属、牛膝菊属、藜属、荨麻属、千里光属、苋属、马齿苋属、苍耳属、旋花属、番薯属、蓼属、田菁属、豚草属、蓟属、飞廉属、苦苣菜属、茄属、蔊菜属、节节菜属、母草属、野芝麻属、婆婆纳属、苘麻属、刺酸模属、曼陀罗属、堇菜属、鼬瓣花属、罂粟属、矢车菊属、车轴草属、毛茛属和蒲公英属。

实施例A
出土前试验
溶剂:5份(重量)丙酮
乳化剂:1份(重量)烷基芳基聚乙二醇醚
为了制备合适的活性化合物制剂,将1份(重量)活性化合物与所述数量的溶剂混合,加入所述数量的乳化剂,用水将此浓缩物稀释到所要求的浓度。
将试验植物的种子播种在普通土壤中,24小时后用活性化合物的制剂浇灌。最好是保持每单位面积上的水量恒定。制剂中活性化合物的浓度并不重要,起决定性作用的只是每单位面积施加的活性化合物的数量。三周后,与未处理的对照样的生长情况比较,将植物的损伤程度按损伤%分级。各数字代表:
0%=无作用(与未处理的对照样相近)
100%=完全摧毁
与先有技术相比,本试验(例如以下制备实施例的化合物:2、3、4、5、6、8、9和11)显示出明显的更好的活性。
