CAS 557-20-0: Diethylzinc

Description: Diethylzinc, with the CAS number 557-20-0, is an organozinc compound characterized by its highly reactive nature, particularly with moisture and air. It appears as a colorless liquid and is known for its flammability. Diethylzinc is primarily used as a reagent in organic synthesis, particularly in the formation of carbon-carbon bonds through reactions such as the Grignard reaction. Its reactivity stems from the presence of zinc, which can readily donate electrons, making it a strong nucleophile. When exposed to water or humid air, diethylzinc reacts vigorously, producing zinc hydroxide and releasing flammable ethane gas, which poses significant safety hazards. Due to its reactivity, it must be handled in an inert atmosphere, typically under nitrogen or argon, and stored in tightly sealed containers. Additionally, diethylzinc is utilized in the production of various organometallic compounds and in the semiconductor industry for the deposition of zinc oxide films. Proper safety precautions, including the use of personal protective equipment, are essential when working with this compound.
