Methyl magnesium chloride is a chemical compound selected from the group of the Grignard compounds, which belong to the metallo-organic compounds.

Production and representation

Methyl magnesium chloride can be obtained by reaction of methyl chloride with magnesium in tetrahydrofuran:

Properties

Methyl magnesium chloride is made available commercially as a solution in tetrahydrofuran in the trade and is in this case a yellow liquid. Can crystallize as a solid at temperatures below 0 ° C from methyl magnesium chloride.

Use

Methyl magnesium chloride (for example, nucleophilic substitution ) is used as Grignard reagent in the synthesis of organic compounds. The lower reactivity with methyl magnesium bromide allowed milder reaction conditions.
