标题:新型含联苯醚的嘧啶胺衍生物的设计,合成,杀虫和杀螨活性
摘要:设计并合成了一系列含有联苯醚部分的原始嘧啶胺衍生物.通过1 H NMR,Ms和元素分析确认了它们的结构.测试了它们对鳞翅目和半翅目昆虫的杀虫活性和杀螨活性.生物测定的结果表明,9K显示最佳活性(lc 50 = 2.08毫克/升)抗二斑叶螨,这是与阳性对照,螺虫乙酯(lc可比50 = 2.27毫克/升),和9克显示出更好的活性(lc相对于阳性对照吡虫啉(lc 50)对抗蚜虫的50 = 0.52 Mg / L) 浓度为(1.02 Mg / L),并且 抗荨麻疹的相对活性较高(lc 50 = 2.49 Mg / L).它们的结构活性关系表明,嘧啶环4位上的乙基和作为苯环对位取代基的烷基链均显示出非常好的生物活性.

标题 :Formamidine sulfate and phosphate salts, their production and their use in the synthesis of 1,3,5-triazine

摘要:The invention relates to the use of formamidine salts of the general formula (I): (NH2-CH=NH2)nHx-nY, where Y is SO4, x is 2 and n is between 0.1 and 2.0, or Y is PO4, x is 3 and n is between 0.1 and 3.0. The salts obtained in accordance with the invention are especially easy to prepare from the technical perspective and make it possibly to produce high yields of highly pure 1,3,5-triazine by thermal decomposition of the corresponding formamidine salts.
