Description
Изобретение относитс к области получени соединений, которые могут найти применение в синтезе физиологически активных веществ, полимеров и сополимеров.The invention relates to the field of the preparation of compounds which can be used in the synthesis of physiologically active substances, polymers and copolymers.
Предлагаетс способ получени винилового эфира р-(фурил-2) акриловой кислоты, заключающийс в том, что |3-(фурил-2) акриловую кислоту подвергают взаимодействию с винилацетатом в присутствии эфирата трехфтористого бора и ацетата ртути с последующим выделением полученного продукта известным способом. Выход продукта 60%.A method is proposed for preparing p- (furyl-2) acrylic acid vinyl ester, consisting in that | 3- (furyl-2) acrylic acid is reacted with vinyl acetate in the presence of boron trifluoride etherate and mercury acetate, followed by isolation of the resulting product in a known manner. The yield of 60%.
Пример. В трехгорлую круглодонную колбу емкостью 50 лы, снабженную механической мешалкой, обратным холодильником с хлоркальциевой трубкой и термометром, помещают 20 мл свежеперегнанного винилацетата , 6,28 г р- (фурил-2) акриловой кислоты, 0,1 мл эфира трехфтористого бора и следы гидрохинона. После тщательного перемешивани содержимого колбы добавл ют 1 г ацетата ртути. Персмещиваиие продолл ают при 40°С в течение 30 мин. Затем реакционную смесь выливают в 120 мл 5%-ного раствора карбоната натри . После отделени органический слой сушат над поташом, отгон ют избыток винилацетата, а оставшеес вещество перегон ют в вакууме в токе азота. После вторичной разгонки получают 4,5 г (60,3%) с т. кип. 89,5-90,5°С/4 Л1М рт. ст., df 1,1165. 1,5835.Example. In a three-neck round-bottom flask with a capacity of 50 liters, equipped with a mechanical stirrer, a reflux condenser with a calcium chloride tube and a thermometer, place 20 ml of freshly distilled vinyl acetate, 6.28 g of p- (furyl-2) acrylic acid, 0.1 ml of boron trifluoride ether and traces of hydroquinone . After thoroughly mixing the contents of the flask, 1 g of mercury acetate is added. The displacement is continued at 40 ° C for 30 minutes. Then the reaction mixture was poured into 120 ml of 5% sodium carbonate solution. After separation, the organic layer is dried over potash, the excess vinyl acetate is distilled off, and the remaining substance is distilled under vacuum in a stream of nitrogen. After the secondary distillation, 4.5 g (60.3%) are obtained with m kip. 89.5-90.5 ° С / 4 Л1М рт. Art., df 1,1165. 1.5835.
