lithium allyl химические свойства, назначение, производство
Использование
Lithium allyl is used as an allyling agent in substitution and addition reactions; used to attach allylic groups to other metals and nonmetals.Подготовка
Lithium allyl is prepared from allyl phenyl ether and Li in THF/ether is recommended for large scale, tinlithium exchange between allyltins and phenyllithium for pure samples.9 Halogen-metal exchange is impractical due to fast Wurtz coupling. Allyllithium can also be made at -78 °C by the reaction of nButyllithium with allyl methyl (or phenyl) selenide,10 and by metallating propene with butyllithium.lithium allyl запасные части и сырье
