Description
Magnesium Diethyl, also known as Diethylmagnesium, is an organomagnesium compound with the chemical formula (C2H5)2Mg. It is a colorless liquid that forms solvated crystals from ether, (C2H5)2Mg·(C2H5)2O, and loses its ether of crystallization when heated under vacuum. Magnesium Diethyl freezes at 0°C (32°F) and decomposes at 250°C (482°F) under high vacuum. It is soluble in ether and is commonly used as an intermediate in inorganic synthesis.

Health Hazard
Skin contact can cause severe burns.
Fire Hazard
Diethylmagnesium catches fire spontaneously
in air. It is susceptible to glow and can catch
fire in other gases, as well, that contain oxygen
atoms in the molecules, such as N2O and even
CO2. It explodes with water. The ether solution
of the compound is also susceptible to
ignition, upon contact with water (Bretherick
1995). It reacts violently with lower alcohols
and ammonia (Sidgwick 1950).
Safety Profile
Ignites on contact with
moist air, water, or carbon dioxide. See also

Check Digit Verification of cas no
The CAS Registry Mumber 557-18-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,5 and 7 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 557-18:
(5*5)+(4*5)+(3*7)+(2*1)+(1*8)=76
76 % 10 = 6
So 557-18-6 is a valid CAS Registry Number.

Organomagnesium reagents enable swift and versatile derivatisation of diarylimines to the corresponding α-substituted diarylmethylamines in excellent yields, through fast and clean reactions. Where it occurs, 1,2-reduction can be circumvented using readily accessible dialkylmagnesium reagents. This journal is
New Syntheses with Magnesium Hydride. Part 1: Hydromagnesiation of α-Olefins to Magnesium-dialkyls
Knott, Wilfried,Klein, Klaus-Dieter
, p. 914 - 918 (2007/10/02)
The addition of highly active magnesium hydride to α-olefins, hydromagnesiation, is a well known reaction.The use of cheap magnesium hydride exhibiting a lower reactivity is highly desirable for industrial purposes.In a combination of chemical and mechanical activation the low reactivity of high temperature magnesium hydride could be overcome thereby making a broad variety of magnesium alkyls accessible. Key words: Magnesium alkyls; hydromagnesiation; magnesium hydride.
