摘要： New organic phosphorus compounds having the formula ##STR1## wherein R.sub.1 represents an alkyl group of 1-4 carbon atoms, R.sub.2 represents an alkoxy group of 1-4 carbon atoms or phenyl group and R.sub.3 represents hydrogen atom, an alkyl group of 1-4 carbon atoms, phenyl group or the group of the formula -X-R.sub.4 in which R.sub.4 represents an alkyl group of 1-6 carbon atoms or a benzyl group which may be substituted with a halogen atom in the phenyl moiety and X represents oxygen atom or sulfur atom. The present compounds are prepared by reacting a phosphoric or phosphonic acid halide having the formula ##STR2## wherein R.sub.1 and R.sub.2 are as defined above and Y represents a halogen atom with a pyridazinone derivative having the formula ##STR3## wherein R.sub.3 is as defined above. The present compounds show a superior insecticidal activity against various harmful insects, e.g., rice stem borers, planthoppers, mites, aphids, flies, mosquitoes and the like and thus they are useful as an insecticide or acaricide.
摘要翻译：具有式“IMAGE”的新的有机磷化合物，其中R1表示1-4个碳原子的烷基，R2表示1-4个碳原子的烷氧基或苯基，R3表示氢原子，1-4个碳原子，苯基或式-X-R4的基团，其中R4表示1-6个碳原子的烷基或可在苯基部分被卤素原子取代的苄基，X表示氧原子或硫原子。本发明化合物是通过使具有式“IMAGE”的磷酸或膦酸卤化物，其中R 1和R 2如上所定义，Y代表卤素原子与具有式“IMAGE”的哒嗪酮衍生物反应，其中R 3如上定义。本发明化合物对各种有害昆虫例如稻螟，蚱蜢，螨虫，蚜虫，苍蝇，蚊子等具有优异的杀虫活性，因此可用作杀虫剂或杀螨剂。
