Abstract

Abstract Diethyl zinc was the first synthetic organometallic compound. The preparation of dialkyl zinc from zinc and alkyl iodide is called the Frankland reaction. Alkyl zinc has found many applications in organic synthesis because because the addition of alkyl zinc to aldehydes in the presence of a chiral catalyst affords secondary alcohols with a high level of enantioselectivity. Besides this, the direct preparation of dialkyl zinc from alkyl iodide and zinc followed by distillation is best for compounds with a short hydrocarbon chain (e.g., from C1 to C4). Several other methods have also been developed for the preparation of of dialkyl zinc.
