[edit] ER vs ee

My impression is that ee is being supplamented by er, which has a more direct thermodynamic meaning and is now recommended by organic chemistry community.--Smokefoot (talk) 03:22, 20 December 2007 (UTC)

  • I have yet to see it in use in organic chemistry articles. V8rik (talk) 16:34, 20 December 2007 (UTC)
Which community? I think I missed the memo. ;-) I still see plenty of papers using ee in 2007, and I don't remember ever seeing one using er. Just because someone wrote and article criticizing ee, doesn't mean that people will actually stop using it. There is a lot of inertia and network effects, not to mention the relatively little gain with the change. --Itub (talk) 16:43, 20 December 2007 (UTC)
You're right, not many people do this. The er thing was just something that stuck in my mind. And I have zero interest in fighting inertia or becoming a reformer of the way it should be" which we see too much of already in these pages.--Smokefoot (talk) 18:26, 20 December 2007 (UTC)
  • ~Interestingly I came across this article:

Are Oxazolidinones Really Unproductive, Parasitic Species in Proline Catalysis? - Thoughts and Experiments Pointing to an Alternative View Helvetica Chimica Acta Volume 90, Issue 3, Date: March 2007, Pages: 425-471 Dieter Seebach, Albert K. Beck, D. Michael Badine, Michael Limbach, Albert Eschenmoser, Adi M. Treasurywala, Reinhard Hobi, Walter Prikoszovich, Bernard Linder doi:10.1002/hlca.200790050

from which I can quote two organic chemistry big guns:

er = enantiomer ratio; we do strongly favor the abandonment of the old-fashioned term ee

So there is still hope! V8rik (talk) 21:10, 3 January 2008 (UTC)

  • I agree with smokefoot on this one, attitudes certainly seem to be moving towards er, but perhaps more importantly it's much easier to understand for a non-chemist! surely this is the most important thing?
    • The current JACS & Org Let asap abstracts show both being used (more ee's on JACS, the same equal numbers on OL). Notable use of er by Bill Roush & Ben List, and ee by Trost. Far from settled Seansheep (talk) 13:51, 24 April 2008 (UTC). edited: Seansheep (talk) 13:55, 24 April 2008 (UTC)
