Diethyl Zinc possible synthsis?
I am looking to synthesize Diethyl Zinc and after doing a little bit of preliminary googling I found this: http://www.orgsyn.org/demo.aspx?prep=CV2P0184
I am wondering if this is a legitimate procedure for the prep of Diethyl Zinc, also if anyone has done this exprment or has synthesized Diethyl Zinc
themselves?
Nota benne, I know about the pyrophoric behavior of Diethyl Zinc and I am equipped to handle this compund in an inert environment.

Orgsyn is a very trusted website. I wouldn't doubt this procedure.

I second thesmug, Orgsyn is very well known and trusted. I have found some great syntheses there.

The Copper-Zinc Couple and its Effects
http://books.google.com/books?id=kAYAAAAAMAAJ&pg=RA1-PA1...
Several years back I was interested in the copper-zinc couple, and tried different things with it. I tried a Barbier type reaction using a few drops
of isopropyl bromide and acetone in a test tube. The reaction was pretty vigorous with slight heating and sonication in the ultrasonic cleaner tank.
One thing you could try with this would be the addition of heated ultrasonic agitation. It may enable you to use 100% ethyl bromide instead of the
(more expensive) ethyl iodide. The use of ultrasonics tends to keep the surface of the couple clean and minimize the deleterious effects of moisture.

Given that this is obviously the first time you hear about the Organic syntheses journal, I'm pretty much confident that you are bluffing
about your abilities to safely deal with such hazardous chemicals. Nobody who has any experience in organic synthesis could remain oblivious of
Organic syntheses. And nobody who does not have sufficient experience should deal with highly pyrophoric materials.
If you play with fire...
…there is a human touch of the cultist “believer” in every theorist that he must struggle against as being
unworthy of the scientist. Some of the greatest men of science have publicly repudiated a theory which earlier they hotly defended. In this lies their
scientific temper, not in the scientific defense of the theory. - Weston La Barre (Ghost Dance, 1972)

I have been an organic chemist for 30 years and not once did I need to or want to make my own diethyl ether. I recommend going to Sigma Aldrich and
download the bulletin on handling pyrophoric chemicals. Every time I used this material I had a face shield, fireproof lab coat, rubber gloves (not
the disposable ones which are too thin) and a class D fire extinguisher. I use stainless steel cannula, gastight syringe, nitrogen to fill the void
by drawing out the solution from the bottle.
