也可以使R1和R2,或者使R1、R2和Z结合。最好R1和R2与处于中间的氮原子一起代表一个叠氮基或者一个选自吡咯烷、哌啶、氢化噁嗪或三唑中的含氮杂环;或者R1、R2和Z与处于中间的氮原子和碳原子一起代表一个二唑环或氢化二嗪环。
本发明还提供了一种制备具有上述定义的通式Ⅰ肼基二苯醚类的方法,其中包括使通式为HNR1R2的胺与通式为Ⅱ的腙基囟反应:
其中Hal代表囟(最好是氯)原子,其它取代基与上述定义的相同。当R1、R2和Z与处于中间的氮原子和碳原子共同代表一个环状基团时,这种物质可以用与使通式Ⅱ腙基囟与乙二胺或其适当衍生物反应的类似方法加以制备。此反应可以在室温下进行,但通常加热以加速反应,并适宜于在回流条件下进行反应。
通式为Ⅱ的原料腙基囟(Z不是烷基或氢)可以通过将通式为Ⅲ的苯胺衍生物重氮化,然后与通式为Ⅳ的囟酰基化合物偶合的方法制备。
其中n、A、X和Y与上面通式Ⅰ中定义的相同;
其中Hal代表囟(优选氯)原子,R代表烷基(适宜的是甲基),而且Z和R3与上面通式Ⅰ中的定义相同(除Z不是烷基或氢之外)。
通式Ⅲ化合物的重氮化和偶合反应是在这类反应的公知条件下进行的,即在0.~10℃之间温度下,用碱金属亚硝酸盐和无机酸进行重氮化反应,在室温下进行偶合反应。
通式为Ⅱ的原料腙基囟(Z是烷基或氢原子)可以按下述方法制备:使通式为R3NH-NH2的肼与通式为Ⅴ的硝基化合物
反应,通式与酸或其酐或通式为ZCOOH或ZCOHal的酰囟反应使得到的苯肼酰化,然后再与五氯化磷反应。其中Z是烷基或氢,而且Hal代表囟(最好是氯)原子。硝基化合物和肼化合物的反应,以及随后的酰化反应,最好都在如二噁烷或甲苯之类惰性有机溶剂中进行,而且酰化反应在囟化氢接受体(较适宜的为有机碱,如三乙胺)存在下进行为好。与五氯化磷的反应最好不用溶剂,在温热下(加热至60~80℃为宜)进行。
当所需的最终产物为Z代表烷基氨基的通式Ⅰ化合物时,可以利用胺化其中Z代表磺酰基的通式Ⅱ腙基囟的方法制备。此化合物含有两个离去基团,即囟原子和磺酰基,而且与胺HNR1R2反应后由-NR1R2置换此二基团,从而制成其中Z是烷基氨基的产物。
当所需的最终产物为其中Z代表氨基甲酰基的衍生物时,可以利用其中Z为氨基甲酰基的适当囟代酰基化合物,或者在方便时通过合成其中Z为烷氧羰基(例如甲氧羰基)的通式Ⅱ化合物,使该脘基囟与胺反应,用-NR1R2取代囟原子,然后进一步使产物与相同或不同的胺反应,置换Z中烷氧羰基取代基的烷氧基部分的方法制备。随着碱HNR1R2空间性质和电性质的不同,烷氧基的置换可能与囟原子的置换同时发生。
已经发现,通式Ⅰ化合物显示出有意义的除草活性。因此,本发明还提供了一种除草组合物,其中含有如上定义的通式Ⅰ化合物和至少一种载体;以及这种组合物的制备方法,其中包括使通式Ⅰ化合物与至少一种载体混合。
本发明还提供了本发明的这类化合物或组合物作为除草剂的用途。而且本发明还提供了通过用本发明化合物或组合物处理某位点以抑制不需要的植物生长的方法。可以对位点作芽前处理或芽后处理,使用的活性成分剂量可以为0.05~4千克/公顷。
本发明组合物中的载体是这样一种材料,将其与活性成分配制成制剂后便于在欲处理的位点(例如可以是植物、种籽或土壤)使用,便于贮存、运输和处理。载体可以为固体或液体(包括通常为气体,但是已压缩成液体的物质),而且可以使用制备除草组合物时通常使用的任何载体。本发明的优选组合物含有0.5~95%(重量)活性成分。
适用的固体载体包括天然的和合成的粘土和硅酸盐,例如硅藻土之类的天然硅石,滑石之类的硅酸镁类;硅镁土和蛭石之类的硅酸镁铝类;高岭石、蒙脱土和云母之类的硅酸铝类;碳酸钙;硫酸钙;硫酸铵;合成的水合氧化硅类和合成的硅酸钙类或硅酸铝类;碳和硫之类的单质;天然树脂和合成树脂,例如香豆酮树脂、聚氯乙烯和苯乙烯聚合物类和共聚物类;固体多氯酚类;沥青;石蜡类以及如过磷酸钙等固体肥料。
适用的液体载体包括水;醇类(例如异丙醇和乙二醇);酮类(例如丙酮、甲乙酮、甲基异丁基酮和环己酮);醚类;芳族或芳代脂族烃(例如苯、甲苯和二甲苯);石油馏分(例如煤油和轻矿物油类);囟代烃(例如四氯化碳、氯乙烯和三氯乙烷)。不同液体的混合物也常常适用。
农业用组合物常常配制成浓缩制剂形式运输,这种浓缩制剂在使用前由用户加以稀释。存在少量表面活性剂载体有利这种稀释过程。因此,本发明组合物中最好至少有一种载体是表面活性剂。例如组合物至少可以含有两种载体,其中至少一个载体是表面活性剂。
表面活性剂可以是乳化剂、分散剂或湿润剂,而且可以是非离子型或离子型表面活性剂。适用的表面活性剂实例包括聚丙烯酸类和木素磺酸类的钠盐或钙盐;分子中含有至少12个碳原子的脂肪酸类或脂肪族胺类或酰胺类与环氧乙烷和/或环氧丙烷的缩合物;丙三醇、山梨糖醇、蔗糖或季戊四醇的脂肪酸酯类;这些物质与环氧乙烷和/或环氧丙烷的缩合物;脂肪醇或烷基酚类(例如对辛基酚或对辛基甲酚)与环氧乙烷和/或环氧丙烷的缩合产物;这些缩合产物的硫酸盐或磺酸盐;分子中含有至少10个碳原子的硫酸酯或磺酸酯的碱金属或碱土金属盐(最好是钠盐),例如十二烷基硫酸钠、仲烷基硫酸钠类、磺化蓖麻油钠盐类和烷芳基磺酸钠类如十二烷基苯磺酸盐;以及环氧乙烷的聚合物和环氧乙烷与环氧丙烷的共聚物。
可以把本发明的组合物制成可湿性粉剂、粉剂、颗粒剂、溶液、乳油、乳状液、浓悬浮液和气雾剂。可湿性粉剂通常含有25、50或75重量%活性成分,而且除惰性固体载体之外,通常含有3~10重量%分散剂,必要时还含有0~10重量%稳定剂(一种或多种)和/或渗透剂或粘着剂等其它添加剂。粉剂通常加工成除无分散剂外与可湿性粉剂的组成相似的母粉,在回间再用另外的固体载体加以稀释,制成通常含0.5~10重量%活性成分的组合物。颗粒剂通常制成粒度为10~100英国标准筛目(1.676~0.152mm)的颗粒,而且可以用附聚法或浸渍法制造。一般来说,颗粒剂含有0.5~75重量%活性成分和0~10重量%诸如稳定剂、表面活性剂、缓释改性剂和粘着剂之类添加剂。所谓“流动性干粉剂”是由含相当高浓度活性成分的相当小的颗粒组成的。乳油除含有溶剂和必要时的助溶剂之外,通常含有10~50w/v%活性成分、2~20w/v%乳化剂和0~20w/v%例如稳定剂、渗透剂和腐蚀抑制剂之类的其它添加剂。浓悬浮液通常配制成一种稳定的、不沉降的流动性产物,而且通常含有10~75重量%活性成分、0.5~15重量%分散剂、0.1~10重量%悬浮剂(例如保护胶体和触变剂)和0~10重量%的例如消泡剂、腐蚀抑制剂、稳定剂、渗透剂和粘着剂之类其它添加剂,以及活性成分在其中基本不溶的水或有机液体;某些有机固体或无机盐可以溶解在制剂中,以便于阻止沉降或者作为水的防冻剂。

除草活性
为了评价本发明化合物的除草活性,使用具有代表意义的植物试验了这些化合物,所用的试验植物有:玉蜀黍(MZ)、稻(R)、稷(BG)、燕麦(O)、亚麻子(L)、芥末(M)、甜菜(SB)和大豆(S)。
试验分成两类:芽前和芽后。芽前试验包括在刚播种了上述植物的种子的土壤上,喷布本发明化合物的液体制剂。芽后试验包括两种试验,即土壤湿润试验和叶面喷布试验。在土壤湿润试验中,用含有本发明化合物的液体制剂湿润生长籽苗植物的土壤,而在叶面喷布试验中则用这种制剂喷淋这些籽苗植物。
这些植物中所用土壤是配制的园艺沃土。
试验中使用的制剂是由试验化合物溶于丙酮而制成的,此丙酮溶液中含有0.4重量%的烷基酚-环氧乙烷的缩合物(市售商标为TRITONX-155)。用水稀释此丙酮溶液,并且按照一定剂量水平使用得到的制剂:在土壤喷布试验和叶面喷布试验中,使用的剂量相当于每公顷5千克或1千克活性物质,相当于每公顷600升;在土壤湿润试验中使用的剂量相当于每公顷10千克活性物质,相当于每公顷大约3000升。
在芽前试验和芽后试验中,分别使用未处理的已播种土壤和未处理的孕育植物籽苗的土壤作为对照。
在叶面和土壤喷布后,利用目测观察12天的方法评价试验化合物的除草效果;在土壤湿润后,利用目测观察13天的方法评价试验化合物的除草效果,并将这种除草效果分0-9个等级记录。0级表示象未处理的对照土壤那样生长,9级表示死亡。在线性分度上每增加1个单位,大约相当于除草效果增加10%。
这些试验结果示于表Ⅲ中。
