Abstract

В настоящем изобретении предусмотрен способ получения азоксистробина, который осуществляют путем проведения реакции между 2-цианофенолом или его солью и соединением, представленным формулой I, при катализе с помощью триметиламинового катализатора с получением азоксистробина, представленного формулой II, который обеспечивает выход продукта, представляющего собой азоксистробин, составляющий 98% или больше, выход отделенного продукта, составляющий 95% или больше, и упрощение последующей обработки. Триметиламиновый катализатор можно регенерировать и повторно использовать в осуществлении синтеза целевого продукта, представляющего собой азоксистробин, что не только снижает стоимость, но также снижает содержание общего азота и COD в отработанной воде. Преимущества способа согласно настоящему изобретению в отношении стоимости и защиты окружающей среды являются значительными и, таким образом, данный способ является пригодным для промышленного производства.
