[en] Data on addition reactions of organic lithium and element organic lithium compounds at multiple carbon-carbon bonds of 1,3-enyl hydrocarbons and their derivatives (alcohols, ethers, amines, etc.) have been classified and generalized in the review. Data on reactions of lithium alkyl adducts and 1,3-enyl hydrocarbons featuring double reactivity with organic compounds of different classes have been generalized

[en] Products of interaction between ethylstrontiumiodide (1) and 1-trimethylsilyl-3-buten-1-yne (2) in tetrahydrofuran solution were studied by the methods of IR spectroscopy and gas-liquid chromatography. It was ascertained that 1 is added via aliquot bonds of 2 in the ratio 1:1 with formation of strontium-containing adduct, its treatment by water giving rise to formation of a mixture (1:1) of alkene and acetylene silicon-containing hydrocarbons with 20% yield

Методами ИК спектроскопии и газо-жидкостной хроматографии изучены продукты взаимодействия этилстронцийиодида (1) с 1-триметилсилил-3-бутен-1-ином (2) в растворе тетрагидрофурана. Установлено, что 1 присоединяется по кратным связям 2 в соотношении 1:1 с образованием стронцийсодержащего аддукта, при обработке которого водой с выходом 20% образуется смесь (1:1) алленового и ацетиленового кремнийсодержащих углеводородовJournal

[en] Interaction of 1-diethylamino-4-pentene-2-ine with ethylstrontium-and ethylbarium iodides has been studied. It has been ascertained that ethylstrontium and ethylbarium iodides are added in the medium of absolute tetrahydrofuran with a high regioselectivity over multiple bonds of 1-diethylamino-4-pentene-organometallic intermediate products, their pyrolysis by water giving rise to ∼40% allene amine formation. Radical of organometallic compounds is fixed near the edge carbon atom of unsubstituted vinyl group
