Application

Methyllithium can methylate a variety of functional groups, can remove protective groups, synthesize other methylated organometallic reagents, can be used as a base and reduce transition metals. Solvents and halogens have a great influence on the reaction using non-solvated methyl lithium. Lithium methyl is a common organic base and methylation reagent, widely used in organic synthesis and catalyst.
