INTRODUCTION

Methyl magnesium chloride is the simplest of Grignard’s reagents. The neat molecule is sensitive to air and moisture. Therefore, it is offered as solution in THF with variable molarity values. At low temperature, it may crystallize out as THF complex and regain solution form at ambient temperature.

Manufacture
The product is manufactured by reaction of chloromethane with magnesium in anhydrous diethyl ether. The synthesis generally requires presence of an initiator.
