Abstract
Изобретение касаетс гетероциклических соединений, в частности способа одновременного получени морфолинотрифторсульфурана и морфолинофторметана, используемых в качестве фторирующих агентов в органическом синтезе. Цель - создание нового способа одновременного получени указанных соединений при увеличении их выходов и упрощении процесса. Синтез ведут из бис(морфолино)-метана и тетрафторида серы при (-50-(-70)°С с последующим разделением целевых продуктов перегонкой в вакууме. В этих услови х выход морфолинофторметана 85-93%, морфолинотрифторсульфурана 83-890%. 1 табл.The invention relates to heterocyclic compounds, in particular, the method of simultaneous production of morpholinotrifluorosulfuran and morpholinofluoromethane, used as fluorinating agents in organic synthesis. The goal is to create a new way to simultaneously obtain these compounds while increasing their outputs and simplifying the process. Synthesis is carried out from bis (morpholino) -methane and sulfur tetrafluoride at (-50 - (-70) ° C), followed by separation of the target products by distillation in vacuum. Under these conditions, the yield of morpholinofluoromethane is 85-93%, morpholinotrifluorosulfuran is 83-890%. 1 tab.
Description
Изобретение относитс к области органической хими, конкретно к способу одновременного получени мор- фолинотрифторсульфурана, который используют в качестве селективного фторирующего агентаэ и морфолинофтор- метана, используемого в качестве источника негидратированного фторид- иона в органическом синтезе.The invention relates to the field of organic chemistry, specifically to a method for the simultaneous production of morpholino trifluorosulfuran, which is used as a selective fluorinating agent and morpholino fluoromethane, used as a source of non-hydrated fluoride in organic synthesis.
Цель изобретени - разработка нового способа одновременного получени морфолиН отрифторсульфурана и морфолинофторметана, увеличение выхода ч упрощение технологии получени и выделени целевых продуктов.The purpose of the invention is the development of a new method for the simultaneous production of morpholine Nrifluorosulfuran and morpholino fluoromethane, an increase in the yield and simplification of the technology for the production and isolation of target products.
Поставленна цель достигаетс тем что бис(морфолино)метан подвергаютThe goal is achieved by the fact that bis (morpholino) methane is subjected to
взаимодействию с тетрафторидом серы при (-50)-(-70)°С с последующим разделением целевых продуктов.the interaction with sulfur tetrafluoride at (-50) - (- 70) ° C, followed by separation of the target products.
Пример 1. В трехгорлую колбу , снабженную углекислотным обратным холодильником, мешалкой и капельной воронкой, при охлаждении до -60°С конденсируют 10,8 г (0,1 моль) тет- рафторйда серы и по капл м добавл ют 18,6 г (0,1 моль) бис(морфоли- но)метана. Реакционную смесь отогревают до комнатной температуры и отгон ют 10,8 г (91%) морфолинофторметана , т.кип. 45-46°С (12 мм рт.ст.), и 15,6 г (89%) морфолинотрифторсуль- фурана, т.кип, 58-60°С (1 мм рт.ст.),Example 1. In a three-necked flask equipped with a carbon dioxide reflux condenser, a stirrer and an addition funnel, while cooling to -60 ° C, 10.8 g (0.1 mol) of sulfur tetrafluoride are condensed and 18.6 g ( 0.1 mol) bis (morpholino) methane. The reaction mixture is warmed to room temperature and 10.8 g (91%) of morpholino fluoromethane is distilled off, b.p. 45-46 ° C (12 mm Hg), and 15.6 g (89%) morpholino trifluorosulfuran, bp, 58-60 ° C (1 mm Hg),
