这个反应,作为平行的德国申请NO. P 43 37 321.6的主题,可由下面的反应路线表示:
式Ⅳ的环状缩醛与式Ⅴ盐的反应以及随之与式Ⅲ杂环的反应可在同一反应容器中直接进行,得到活性化合物Ⅰ。在这种情况下,盐R1′M,该化合物也可在原位由化合物R1′H制备,而碱应首先加入。然后再加入式Ⅲ杂环。式Ⅲ化合物最好在反应第一步,即式Ⅴ盐加到中间式体Ⅳ中的反应基本完成后加入。该反应可持续数分钟到几小时,反应温度为-40℃-200℃,通常0℃-130℃。
也可以在第一步反应后中止反应并分离出中间体Ⅱ(其中R1=R1′),并可如上所述进一步反应。
在这两种情况下,常规的溶剂都是适用的,其条件是它们不能被反应中所用的和存在的碱或盐R1′M去质子化。极性溶剂,例如醚类如乙醚、甲基叔丁基醚、二甲氧基乙烷、四氢呋喃、二噁烷、酰胺类如二甲基甲酰胺、二甲基乙酰胺、N-甲基吡咯烷酮和二甲基亚丙基脲或二甲亚砜是特别高度适用的。相转移催化剂如冠醚或季胺盐。如果能促进转化则可被加入。
反应温度为-40-200℃,优选0-160℃。反应时间一般为数分钟到50小时,通常0.5-10小时。
总的来说,对于每摩尔起始物Ⅳ,可使用0.8-3,特别是0.9-1.5摩尔当量的化合物Ⅴ(R1′M)。基于式Ⅰ化合物,杂环Ⅲ的用量同样合适为0.8-3,特别是0.9-1.5摩尔当量。
反应可在常压、加压或减压下连续或不连续进行。
反应完成的可能性是变化的,取决于个别的情况下产物在所采用的溶剂中的溶解度和溶剂与水的互溶性以及溶剂的沸点。在含水和不含水情况下完成反应都是可能的。
一合适的完成反应的方法包括例如使反应混合物混合,其中的溶剂也可事先部分或完全蒸除,与水混合并滤出产物或用有机溶剂萃取。
起始物Ⅳ可优选地通过使6-羟基苯甲酸(Y=0)或6-巯基苯甲酸(Y=S)与化合物0=CR′R″在酸性催化剂存在下反应而制备:
在这种情况下A是卤原子,例如氯、溴或碘、C1-C4卤代烷基磺酰氧基,特别是三氟甲磺酰氧基,C1-C4烷基磺酰氧基或氟代磺酰氧基。
起始物通常是已知的或按常规已知的方式可得到的。
为结合反应中产生的水,可加入脱水剂。象例如分子筛,酸酐,例如三氟乙酸酐、乙酐,硫酸钠或氯化钙,如果这种处理可促进转化的话。化合物O=CR′R″的活性缩酮,例如二甲醇缩醛,二乙醇缩醛、亚乙基二醇缩醛或1,2-亚丙基二醇缩醛,也是适用的。合适的催化剂特别是酸性离子交换剂、质子酸(protic acids)象例如甲苯磺酸、硫酸、磷酸等,或路易斯酸象例如氯化铝、四氯化钛、氯化锌、氯化钙、氯化镁、氯化锡等。通常,由缩醛生成的水或醇可直接由反应混合物中蒸馏除去。
得到环状缩醛Ⅳ的进一步反应的进行是采用式W-Py的甲锡烷基或甲硼烷基化合物,在催化活性的钯化物的存在下,按照下列反应路线进行:
W是三烷基甲锡烷基,例如三-C1-C8烷基甲锡烷基如三甲基甲锡烷基、三乙基甲锡烷基、三丙基甲锡烷基、三丁基甲锡烷基、三戊基甲锡烷基或三己基甲锡烷基,二羟基甲硼烷基、二烷氧基甲硼烷基,例如二-C1-C4-烷氧基甲硼烷基如二甲氧基甲硼烷基、二乙氧基甲硼烷基、二丙氧基甲硼烷基、二异丙氧基甲硼烷基或二丁氧基甲硼烷基或异构体,或亚烷基二氧基甲硼烷基,例如,C1-C4-亚烷基二氧基甲硼烷基,如1,2-亚乙基二氧基甲硼烷基或1,3-亚丙基二氧甲硼烷基。所采用硼或锡化合物或者是已知的或者按类似于已知化合物的方式制备。
在这个新方法中采用催化活性的钯化合物。至少部分能溶于反应混合物的任何有用的钯盐或复合物在本方法中都是适用的。钯的氧化态可为0或2。在钯盐情况下,合适的平衡离子,特别是下述离子:氯、溴、碘、硫酸根、乙酸根,三氟乙酸根、乙酰基丙酮酸根或六氟-2,4-戊烷-二酮根。可采用很多不同的钯复合物,先决条件只是钯上配体可在反应条件下从底物上脱除。膦类配体象例如芳基烷基膦,特别是甲基二苯基膦、异丙基二苯基膦、三芳基膦如,特别是三苯膦、三甲苯膦、三(二甲苯基)膦,三杂芳基膦如三呋喃基膦或二聚膦是特别合适的。烯配体如:特别是二亚苄基丙酮或其盐、环辛-1,5-二烯或胺如三烷基胺(例如三乙胺、四甲基乙二胺和N-甲基吗啉)或吡啶也是特别适合的。
所用的复合物可直接在反应中使用,这个过程可以采用例如四(三苯膦)钯(0)、二氯化双(三苯膦)合钯、双(三苯膦)二乙酸钯、二亚苄基丙酮钯(0)复合物、四(甲基二苯基膦)合钯(0)或双(1,2-二苯基膦基乙烷)二氯化钯。也可采用钯盐和另外适当的配体,然后它们原地仅生成催化活性的复合物。这个过程适合在,例如,在上述盐和膦类配体如,例如三呋喃基膦或三甲苯基膦的情况下使用。钯复合物如,例如三(二亚苄基丙酮)二钯、双(二亚苄基丙酮)钯或1,5-环辛二烯二氯化钯也可通过加入配体如,例如三呋喃基膦或三甲苯基膦而被进一步活化。
常规的,基于化合物W-Py,使用0.001-10mol%,特别是0.005-5mol%的钯化合物(盐或复合物)。更高的用量也是可能的但较不经济。
化合物W-PY的用量,基于起始物Ⅳ-A,通常使用0.8-3,优选0.95-1.5mol当量。
所有本身不与反应底物反应的溶剂对本反应都是适用的。极性溶剂可加速反应。醚如二乙醚、甲基叔丁基醚、二甲氧基乙烷、四氢呋喃和二噁烷,酰胺如二甲基甲酰胺、二甲基乙酰胺、N-甲基吡咯烷酮和二甲基亚丙基脲(dimethylpropyleneurea),或胺如三乙胺,是特别适用的。使用例如醚和酰胺的混合物或上述溶剂与水或脂族醇的混合物常常是优选的,加入四烷基卤化铵或碱金属卤化物如氯化锂常常是有利的,并且当A为磺酰氧基时,特别推荐这种用法。
反应温度为-20℃-200℃,优选50-160℃。反应时间常规为数分钟到50小时,通常0.5-10小时。当使用低沸点溶剂时,将反应在高压釜中于自压下进行有时是有利的。
如果按所述方法制备的式Ⅰ化合物是羧酸(即若R1为羟基),那么制备例如如权利要求2所述的羧酸衍生物也是可能,首先通过常规方式将羧酸转化成其活性形式例如卤化物或酰咪唑(imidazolide),并随后使之与适当的式R1-H羟基化合物反应。这两步骤也可简化,例如,使羧酸与羟基化合物在脱水剂如碳化二亚胺或合适磷酸酐存在下进行反应。
进一步,式Ⅰ羧酸(即其中R1是羟基)也可如下反应得到许多所述的酯:为了做到这一点,首先将羧酸转化成盐,特别是碱金属盐,并随后将之与烷基化剂反应,若需要,可在上述之一的碱的存在下进行。烷基化剂具有通式R1-R21,常规的离去基团如,例如氯、溴、碘、芳基或烷基磺酰基如,例如甲苯磺酰基或甲磺酰基适合作为R21。总的来说,所采用的烷基化剂是已知的或可按类似于已知化合物的方式制备。
作为除草剂,化合物Ⅰ或含有它们及其环境可接受盐的组合物,所述盐例如碱金属和碱土金属盐,可以十分有效地控制作物和小麦、水稻、玉米、大豆、棉花中的阔叶杂草和草地杂草而不伤害作物,特别在低施用率时出现这一效果。

化合物Ⅰ通常适于制备成直接可喷洒溶液、乳化液、糊剂或油分散剂。合适的惰性添加剂为具有中到高沸点的矿物油、如煤油或柴油,或者煤焦油和植物或动物油,脂族烃、环烃和芳香烃,例如石蜡,四氢化萘、烷基化萘或它们的衍生物,烷化苯或它们的衍生物、甲醇、乙醇、丙醇、丁醇、环己醇、环己酮或强极性溶剂,如N-甲基吡咯烷酮或水。
含水施用形式可通过向乳化液浓缩物、悬浮液、糊剂、可湿性粉剂或水分散性颗粒中加水而得到。为制备乳化液、糊剂或油分散液,这样的底物或溶解于油中或溶剂中的底物,可通过润湿剂、添加剂、分散剂或乳化剂在水中均化。但是,由活性物质、润湿剂、添加剂、分散剂或乳化剂以及可能存在的溶剂或油组成的浓缩剂也可制备,它适于用水稀释。
适合的表面活性剂是芳族磺酸和脂肪酸的碱金属盐、碱土金属盐和铵盐、所述芳族磺酸如木素磺酸、苯酚磺酸、萘磺酸和二丁基萘磺酸,烷基磺酸和烷芳基磺酸盐,烷基、月桂基醚和脂肪族醇的硫酸盐,也可为十六、十七和十八碳醇的硫酸化的盐和为脂肪醇乙二醇醚的盐、磺化萘及其衍生物与甲醛的缩合产物,萘或萘磺酸与苯酚和甲醛的缩合产物,聚氧乙烯辛基苯酚醚,乙氧化异辛基,辛基或壬基苯酚,烷基苯酚或三丁基苯酚聚乙二醇醚,烷芳基聚醚醇,异十三烷醇、脂肪醇/环氧乙烷缩合物;乙氧化蓖麻油、聚氧乙烯或聚氧丙烯烷基醚、月桂醇聚乙二醇醚乙酸酯、山梨醇酯、木质-亚硫酸废液或甲基纤维素。
粉剂、撒施剂和撒粉组合物可通过混合或研磨混合活性物质和固体载体而制备。

式Ⅰ化合物还可进一步影响植物的各个发展阶段,因此也可用作生长调节剂。植物生长调节剂的各种作用特别依赖于植物的种类和变种;取决于施用的时间,这是相对于植物发展的阶段而言,和取决于所用季节;取决于施用形式和施用过程(例如种子追肥、土壤处理、施用于叶或当为树时茎注射);取决于气候因素(例如温度、沉淀量、还有白昼长度及日照强度);取决于土壤条件(包括肥力);取决活性化合物的制剂和施用形式以及取决于所用活性物质的浓度。
本发明的式Ⅰ化合物在植物培养中,在农业和园艺学中作为植物生长调节剂施用的一些不同的可能情况,如下如述:
A
本发明使用的化合物可强烈抑制植物生长,这特别在减弱高度生长方面显示出来。因此被处理植物生长得矮壮;还可观察到叶子颜色较暗。
路边、蓠笆、运河岸边的草以及在如公园、运动场和果园、修饰性草坪和机场等地点的草的生长强度降低在现实中是有利的,这样可以减少费力而昂贵的割草。
对倒伏敏感的作物如谷类、玉米、向日葵和大豆,其抵抗力的增加也具有经济价值。在这种情况下使产生的秆变矮和强壮减少或消除了收割前恶劣气候条件下植物倒伏(弯下)的危险。
生长调节剂的施用对抑制高度生长和暂时改变棉花的成熟过程也是重要的。因此使得完全机械化的收割这种重要作物变得可能了。
在水果和其它树的情况下,采用生长调节剂可节省修剪树枝的花费。而且,利用生长调节剂果树的改变可被打破。
通过施用生长调节剂,植物的边枝也可增加或被抑制。这种情况是有价值的,如果边枝(根出条)的形成,将抑制叶的生长,例如在烟草植物情况下。
对于冬油菜,例如,采用生长调节剂也可相当程度地增加对霜冻抵抗力。在这种情况下,一方面,过分繁茂(因此对霜冻特别敏感)的草木植物或生物量的高度的生长和发展被抑制了。另一方面,播种后和冬天霜冻降临前除非有适合的生长条件,小油菜的有生长力的生长阶段停止了。因此,对那些易于对开花抑制的早熟退化,易于转成生殖期的植物的霜冻危险被消除了。甚至对其它作物,例如冬季谷类,如果在秋天采用本发明化合物处理使其数量的确很好地被分蘖,但不过份繁茂,也是有利的。结果是,由于相对少的草本植物或生物量,增加的霜冻敏感性和被各种病害侵扰(例如真菌病)可被阻止。对有生长力生长的抑制还使得土壤被众多作物进行更全面的种植成为可能,因此,在(同样)土壤面积的基础上,可得到额外收获率。
B
采用生长调节剂可以得到的额外收获率包括植物部份和植物组份部份二者。因此,这些是可能的,例如诱导产生更多的芽、花、叶、果实、种子、根和块茎,诱导甜菜、甘蔗和柑橘属水果产生更多的糖、诱导提高谷类和大豆的蛋白质含量和刺激橡胶树增加橡浆流出量。
在这种情况下,式Ⅰ化合物可通过介入植物新陈代谢或促进或抑制植物生长和/或生殖能力的发育而增加产量。
C
最后,减少或延长发展阶段和在收获前或后加速或推迟植物被收获部分的成熟都可通过采用植物生长调节剂完成。
有经济价值,例如,是有利于收获,这通过暂时集中在秋季成熟或在柑橘类水果,橄榄的情况下或在其它种类或变种的苹果、核果和硬壳干果情况下,降低了对树的粘着性而成为可能。同样的机理,即促进植物果实或叶和芽部分之间脱离组织的生长,对于多产植物,例如棉花,的易于控制的落叶也是必要的。
D
通过使用本发明化合物,灌溉强度可以降低,因此可进行更经济的管理。在生长调节剂的影响下,可对现场水的更好的利用,例如,特别是因为气孔开放宽度减小、生成更厚的表皮和角质层、土壤中根的穿透能力提高了以及更的生长有利影响了植物种群的微环境。
式Ⅰ化合物特别适用于秆矮状的作物如大麦、油菜、小麦。
本发明使用的式Ⅰ生长调节剂可通过种子(作为种子处理剂)和经土壤,即通过根,且特别优选的,经过喷洒到叶上,而加到作物上。这里组合物是按除草剂类似的方式制备。
由于高的植物相容性,活性化合物的施用率并不是关键。理想的施用率的变化取决于控制对象、季节、靶标植物和生长阶段。
为加宽作用谱和达到增效效果,将吡啶基水杨醛和水杨酸衍生物Ⅰ与许多代表性的其它除草剂或生长调节活性化合物组混合并一起施用。例如,合适的除草剂混合物组分为:二嗪、4H-3,1-苯并噁嗪衍生物、benzothiadiazinones,2,6-二硝基苯胺、N-苯基氨基甲酸酯、硫代氨基甲酸酯、卤代羧酸、三嗪、酰胺、脲、二苯基醚、trazinones,尿嘧啶、苯并呋喃衍生物、环己烷-1,3-二酮衍生物,其可在2-位带有例如羧基或碳亚氨基(Carbimino)、喹啉羧酸衍生物、咪唑啉、磺酰胺、磺酰脲、芳氧基和杂芳氧苯氧丙酸及其盐、酯和酰胺等等。合适的植物生长调节剂特别为氯化矮壮素阳离子,乙烯和助壮素。
单独采用化合物Ⅰ或与其它除草剂或生长调节剂一同结合使用以及还可进一步与作物保持剂混合,例如与防治害虫或植物致病真菌或细菌的制剂,也是有利的。另外的优点是与用来消除营养和微量元素缺乏状况的无机盐溶液之间的互容性。也可加入非植物毒性油和油浓缩物。

用途实施例
通过温室试验能够显示出式Ⅰ化合物的除草和生长调节作用。
培养容器采用塑料罐,用含3.0%腐殖质的肥土作为底物。试验植物的种子按种类分开播种。
在芽前处理的情况下,在播种后通过精细的分散喷嘴,将悬浮或乳化分散于水中的活性化合物直接施用。容器轻微润湿以提高出芽和生长并用透明塑料膜盖上至到植物长出根顺。如果活性化合物不对试验植物产生不利地影响,这种遮盖将产生一致的发芽。
对于芽后处理,取决于生长型的试验植物首先长到高度3-15cm,直到此时才用悬浮或乳化分散于水中的活性化合物处理。为了做到这一点,使试验植物或者在同样的容器中直接播种和生长或者使它们作为种子植物先单独培养然后在处理前几天移入试验容器中。芽后处理的施用率各自为0.0313或0.0625kg/ha。
植物在10-25℃或20-35℃于每种的特异性方式下维持。试验时间2-4周。在这段时间内,照料植物,记录它们对于各种处理的反应。
除草作用用级别0-100表示。这里100表示无被除植物出现或至少地上部分植物被完全毁灭,以及0表示无损伤或正常生长过程。
生长调节作用通过测量高度测定。在试验末部,测量处理过的植物的生长高度并与未处理过植物的生长高度比较。
温室试验中采用的植物包括下列种类:
结果表明本发明的化合物No.1.004具有很好的除草作用。
与现有技术化合物相比更好的除草作用在下表Ⅰ和Ⅱ中给出。所用被比较物质是具有下述结构的化合物:
表1
温室中芽后分别施用0.0625kg/ha和0.0313kg/ha(a.s.)时除草活性
表2
