Simpler, greener method for producing Grignard reagents

Caption

(Left) Reaction mixture of magnesium metal and organohalide after one hour of ball milling. Use of this material in subsequent reactions led to only a 6% yield of the desired product. (Right) Same process, but with a small amount of organic solvent also added at the beginning. Use of this paste form of Grignard reagent in subsequent reactions led to yields of up to 94% of the desired product (Photo: Koji Kubota).
