Paragraph 0088; 0092-0093, (2021/11/14)
The invention relates to a preparation method of N - alkyl substituted hydroxylamine salt, and belongs to fine chemical engineering. Pesticide or bulk pharmaceutical chemicals technical field. The present invention reacts with the N - alkyl of the oxime with an inorganic salt of hydroxylamine to give N - alkyl-substituted hydroxylamine salt and oxime. The invention provides an efficient and environment-friendly method for preparing N - alkyl substituted hydroxylamine salt, and simultaneously, an N - alkyl substituted hydroxylamine salt is prepared, and the oxime can be re-prepared to form N - alkylate of oxime so as to realize the material circulation. No equivalent acid is used in the reaction process. Alkali neutralization, avoided the current method to use a large amount of acid, alkali and produce inorganic salt solid waste shortcoming, environmental protection more. The preparation method is mild in reaction condition, and the defects of high pollution and high energy consumption of the traditional process are overcome. In-flight R1 , R2 What is R is as claimed in the claims and the description.

Novel benzoylphenylureas containing an oxime ether group were designed and synthesized by four schemes. These benzoylphenylureas were identified by 1H NMR spectroscopy and element analysis (or HRMS). The bioactivities of the new compounds were evaluated. These benzoylphenylureas exhibited excellent larvicidal activities against oriental armyworm, some of which were much better in comparison with the commercial Flucycloxuron. In particular, the larvicidal activities against oriental armyworm of compounds 1 and 23 were 5-10 times better than that of Flucycloxuron. Most of these benzoylphenyureas exhibited excellent larvicidal activities against mosquito. At the same time, some of these compounds have good plant growth regulatory activities as well.
