Daim ntawv thov:
Tsis muaj kev lag luam tseem ceeb ntawm kev siv methyllithium, tab sis nws tau siv dav hauv chav kuaj hauv Grignard hom tshuaj tiv thaiv.
Methyllithium yog ib qho organolithium reagent tsuas yog siv rau deprotonation thiab ua qhov chaw ntawm methyl anion. Nws yog lub hauv paus muaj zog thiab muaj zog nucleophile.
Methyllithium lithium bromide complex tov (MeLi.LiBr) tuaj yeem siv los ua tus neeg sawv cev methylating rau -methylation ntawm alkoxyaryl ketones.
Cia:
Khaws rau hauv qhov chaw txias. Khaws lub thawv kaw kom nruj rau hauv qhov chaw qhuav thiab qhov cua zoo.
