lithium allyl 化学特性,用途語,生産方法
使用
Lithium allyl is used as an allyling agent in substitution and addition reactions; used to attach allylic groups to other metals and nonmetals.
製造方法
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.
