| description | FIELD: chemistry. ^ SUBSTANCE: present invention relates to a method of producing antipyrenes of general formula (I) R = Et, Pr, C6H13, CH2Ph, Ph, 2-CH3OC6H4. The method involves reacting 3,3,5-trimethyl-2-chloro-1,2-oxaphospholene-2-oxide with an organomagnesium compound (Grignard reagent) RMgX (X = Br, I) in a medium of organic solvent in molar ratio 1 : (2.0-2.6) while stirring for 0.5 to 2 hours, hydrolysis of the reaction mass with an aqueous solution of hydrochloric acid, separation of the organic phase and extraction of desired compounds from the organic phase using known methods. ^ EFFECT: design of a new method of producing antipyrenes. ^ 2 cl, 8 ex, 1 tbl
Настоящее изобретение относится к способу получения антипиренов общей формулы (I) ! ! Способ включает взаимодействие в среде органического растворителя ! 3,3,5-триметил-2-хлор-1,2-оксафосфолен- ! 2-оксида (II) с магнийорганическими соединениями (реагентами Гриньяра) RMgX (X=Br, I) в мольном соотношении 1-(2.0-2.6) при перемешивании в течение 0.5-2 часа, ! ! гидролиз реакционной массы водным раствором соляной кислоты, отделение органической фазы и выделение из нее целевых соединений известными приемами. Технический результат - разработка нового способа получения антипиренов. 1 з.п. ф-лы, 1 табл. |
