Description
Предложен способ получени триалкилсилилалкокоиацетиленов путем взаимодействи триалкилгалоидсиланов с магнийорганическими соединени ми алкокоиацетиленов при нагревании в среде эфира с последующим выделением целевого продукта известным способом , например фильтрацией.A method for producing trialkylsilylalkoociacetylenes is proposed by reacting trialkylhalidesilanes with organomagnesium compounds of alkocioacetylenes by heating in ether and then isolating the target product in a known manner, for example by filtration.
Синтезированные соединени могут быть истюльзованы дл получени различных кремнийсодержащих мономеров.The synthesized compounds can be used to obtain various silicon-containing monomers.
Пример. Из 9,3 г (0,39 моль) магни , 44 г (0,40 моль) бромистого этила и 30 г (0,43 моль) этокси ацетилен а в абсолютном эфире приготовлено магнийорганическое соединение , к которому добавлено 50 г (0,33 люль) триметилбромсилана. После кип чени в эфире остаток отфильтровывалс , из фильтрата отгон лс эфир, а остаток фракционировалс . Выделено 25 г (53% теоретического ко ичества ) триметилсилилэтоксиацетилена.

Out of 9.3 g (0.39 mol) of magnesium, 44 g (0.40 mol) of ethyl bromide and 30 g (0.43 mol) of ethoxy acetylene, the organomagnesium compound was prepared in absolute ether, to which 50 g (0, 33 people) trimethylbromosilane. After boiling in ether, the residue was filtered, ether was distilled off from the filtrate, and the residue was fractionated. 25 g (53% of the theoretical value) of trimethylsilyl ethoxyacetylene were isolated.
