Greener, Revolutionary Method for Producing Grignard Reagents
(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.
