Abstract

可用常规方法制得通式(Ⅰ)衍生物:其中A为任意取代的芳基或五、六元含氮杂芳基等;m为0—5、n为0—2的整数;R1为氢、卤、任意取代的烷基、烯基、炔基、烷氧基等;R2为氢、卤、任意取代的烷基、烯基、炔基、烷氧基等;X为氧或硫;Z为氮或CH;条件是:如果A为1－甲基－3－三氟甲基－吡唑－5－基基团。n是0,X为氧且Z为CH,则Rm 2不是氢或3－三氟甲基或2,4－二氯或2,4－二甲基。这类化合物尤其可用作除草剂。

Description

2，6-双取代的吡啶和2，4-双取代的嘧啶除草剂
本发明涉及某些2，6-双取代的吡啶和2，4-双取代的嘧啶，它们的制备及其作为除草剂的应用。
吡啶、嘧啶及其衍生物在药学领域和农业(除草剂、杀真菌剂、杀螨剂、驱虫药、驱鸟剂)、以及用于聚合物和纺织工业的试剂、中间体和化学物品中具有许多用途。
例如，(分别在DE 40 29 654和JO 2131-480中)披露将2-芳基嘧啶和2-嘧啶基-6-芳基吡啶用作杀真菌剂。EP 263,958涉及除草剂2，6-二苯基吡啶；EP354,766和425,247分别描述了结构相关的2，4-二苯基嘧啶类化合物，它们也被说成是除草剂。另一个例子是2，6-二苯氧基吡啶，在EP 572,093中它被作为除草剂。在DE29 35 578中揭示4-苯氧基-2-吡唑-1-基嘧啶具有杀真菌活性。Huelsen(Diplomarbet，Konstanz 1993)描述了四种不同性质的2-(1-甲基-3-三氟甲基-吡唑-5-基氧基)-6-苯基吡啶，但没有披露生物活性。
业已惊奇地发现在同时具有一个芳基和一个芳氧基或杂芳氧基的相关的新吡啶和嘧啶衍生物中，存在着良好的除草活性。在杂草出现前和出现后这些化合物对阔叶和禾草种类杂草都显示出未曾预料的优良的活性和良好的作物选择性。
因此，本发明提供通式I的2,6-取代的吡啶和2，4-取代的嘧啶：

试验可分为两类，出芽前和出芽后。出芽前试验为在刚播撒了上述植物的种子的土地上喷洒化合物的水性制剂。出芽后试验为用所示溶液喷洒上述植株的幼苗。
试验所用的土是制备好的园艺肥土。试验所用的配制剂是用试验化合物的丙酮溶液制备的，其中含油按重量计0.4％烷基苯基/环氧乙烷缩合表面活性剂，其商品名为TRITON X 155。丙酮溶液用水稀释，形成的制剂其剂量水平相当于每公顷(ha)1000g或300g活性物质，按体积计相当于每公顷400L。作为对照，在出芽前试验中使用未处理的播种后土地，在出芽后试验中使用未处理的但已出芽的土地。
在对叶和土地喷洒后20天(如果是实施例13-16化合物，则在喷洒后13天)，目测评价试验化合物的除草效果，并记录为0-9级。0级表示杂草生长情况与未处理的对照相同，9级表示杂草死亡。线性级数中每增加1个单位就表示效果水平增加约10％。星号表示该种植株在试验中没有经过处理。
试验结果见下表，其中，用前述实施例表示化合物。星号表示该种植株在试验中没有经过处理。
