what is "chiral transmission"? I am familiar to the field of chirality in chemistry but this term is new to me. It also doesn't appear a standard IUPAC term. Maybe someone should elaborate on this in the article, instead of devoting only two lines to it. I'm with gerrit 03:38, 6 August 2007 (UTC)

  • I have included the reference that I used for that particular segment. I had never heard of it either but it makes a lot of sense: induction-amplification-transmission. V8rik 20:21, 6 August 2007 (UTC)

Optic resolution[edit]

On the subject: [1] Okay, it's in Dutch, but what it boils down to is that if you stir long and hard enough, you get an optically pure mixture. Whether it's L or D depends on present contaminations (e.g. a human hair in the mixture triggers formation of D-crystals). If anyone could find an English reference, that would be very handy. 78.21.62.169 (talk) 02:12, 13 June 2008 (UTC)

I can't read Dutch, but I've read the JACS article cited there. It doesn't mention anything about hair, but it discusses an experiment in which a racemic mixture of crystals in equilibrium with a basic solution where the compound can epimerize, led to an single enantiomer in the solid state when they added 0.1% of enantiopure phenylglycine. --Itub (talk) 10:04, 13 June 2008 (UTC)
Just because it was originally written in another language, doesn't excuse a lack of readibility. Optical resolution has another definition; if you are using another definition, spell it out. Use plain English. Elucidate! Kortoso (talk) 22:41, 13 December 2013 (UTC)

"Chiral amplification" section of the main article[edit]

Nitrosobenzene condenses with "active" methylene groups, e.g. of malonic esters, benzylcyanide PhCH2CN etc. by scheme:

Ph-N=O + R-CH2-R' => [ Ph-N(OH)-CHRR' ] => Ph-N=CRR' + H2O,

i.e. carbon of the methylene group bonds with nitrogen atom, not oxigen atom of Ph-N=O (and the resulting bond is C-N bond, not C-O bond).

But this image in the #Chiral amplification section:

Scheme 2. Blackmond autocatalysis

shows as methylene of propionaldehyde bonds with oxigen atom of Ph-N=O, forming C-O-bond. Is it a mistake? Krasss (talk) 18:06, 29 September 2009 (UTC)
