Description
Предлагаемый способ получени транс-1,3бис- (пентафторфенил) бутана-1 и само соединение в литературе пе описаны. Это вещество, относ щеес к классу фторолефинов, может найти применение как исходное дл получени пластмасс, каучуков, а также дл синтеза различных органических производных.The proposed method for preparing trans-1,3bis- (pentafluorophenyl) butane-1 and the compound itself are not described in the literature. This substance, belonging to the class of fluoroolefins, can be used as a starting material for the production of plastics, rubbers, as well as for the synthesis of various organic derivatives.
Способ заключаетс во взаимодействии 1-(пентафторфенил) этилового спирта с четырехфтористой серой при нагревании до 80- 120°С с последующим выделением целевого продукта известным методом.The method consists in the interaction of 1- (pentafluorophenyl) ethyl alcohol with sulfur tetrafluoride when heated to 80-120 ° C, followed by separation of the target product by a known method.
Пример. 6г 1-(пентафторфенил)этилового спирта и 6 г четырехфтористой серы нагревают в автоклаве при 100°С в течение 20 час. Реакционную массу обрабатывают водой, экстрагируют эфиром и перегон ют. ПолучаютExample. 6 g of 1- (pentafluorophenyl) ethyl alcohol and 6 g of sulfur tetrafluoride are heated in an autoclave at 100 ° C for 20 hours. The reaction was treated with water, extracted with ether and distilled. Get
