This is not triphos. Triphos is bis-(2-diphenylphosphinoethyl)phenylphosphine (PPh2)-CH2-CH2-P(Ph)-CH2-CH2-(PPh2). —Preceding unsigned comment added by (talk) 15:04, 29 September 2010 (UTC)

  • is it possible triphos is a compound class? The aldrich catalogue lists both triphosphines as triphos. This link agrees with content in the current article. V8rik (talk) 19:20, 29 September 2010 (UTC)
Yes, I saw that too and I have been worried about this ambiguity. We could/should expand the article to discuss both. I am looking for a prep of the linear isomer (CAS#23582-02-7). --Smokefoot (talk) 01:17, 30 September 2010 (UTC)
    • Hi Smokefoot, thanks for clearing up this issue, otherwise very confusing V8rik (talk) 20:20, 30 September 2010 (UTC)

IUPAC Compound "Triphos"Edit

The IUPAC Red Book for Inorganic Nomenclature identifies the "triphos" ligand as such: [(phenylphosphanediyl)bis(ethane-2,1-diyl)]bis(diphenylphosphane)

Neither of the compunds on this page are identified by this name, however, since they are quite nontrivial, I cannot verify if they are identical to the IUPAC Name.

Please note also that the IUPAC source also states that the name triphos should not be used for "PhP(CH2PPh2)3".
