Dimethyl zinc was used for a long time to introduce methyl groups into organic molecules or to synthesize certain organometallic compounds, however, certain reagents which are easier to handle and less flammable, replaced organo-zinc compounds in most laboratory syntheses.
Dimethyl zinc was used for a long time to introduce methyl groups into organic molecules or to synthesize organometallic compounds containing methyl groups. Grignard reagents, (organo-magnesium compounds), which are easier to handle and less flammable replaced organo-zinc compounds in most laboratory syntheses.
