Zn(OMe)2 with readily available Grignard reagents, it was possible to induce the complete precipitation of magnesium salts and then obtain salt-free diorganozinc reagents after centrifugation/filtration. This practical method to generate dialkylzincreagents as well as mixed diorganozinc reagents was successfully tested in various catalyticenantioselectivereactions, proving the purity of the product and
