[edit]I don't see where reference 1 mentions anything about the inverse solubility--Davemody (talk) 14:28, 23 June 2010 (UTC)
Liquid-liquid data from Stephenson clearly show the widening of the miscibility gap with increasing temperature on the water side. [1]

Melting vs glass
[edit]How does it have a melting point if it is a glass former? — Preceding unsigned comment added by 96.231.170.47 (talk) 01:59, 9 November 2015 (UTC)
- A glass is a non-crystalline solid, not a viscous liquid. But more to the point, wikipedia reports what is published in reliable sources (scientific journals), and both the concept of being a glass-former and its mp are reported in the same published article. I adjusted the cites to clarify the mp source. DMacks (talk) 04:07, 9 November 2015 (UTC)
Wool–Rh complex?
[edit]The article currently notes the asymmetric synthesis of Me-THF using a wool–Rh complex. I can't access the ref in question but it seems a terribly odd way of going about it. Is wool a ligand now... are sheep? --Project Osprey (talk) 14:39, 2 July 2021 (UTC)

- is part of the "Special Issue:11th International Symposium on Fine Chemistry and Functional Polymers (FCFP‐XI)". I don't know the terminology that Wiley uses...does this mean it is more of a conference presentation rather than a refereed journal article and therefore less RS? I cannot access the full article either, but (1) it seems reasonable, but (2) WP:UNDUE as written. I'll do some lit-searches when I get a chance. DMacks (talk) 17:19, 2 July 2021 (UTC)

- In the old, old days (1950's), I think that silk was used to support catalysts and some asymmetric induction was observed. --Smokefoot (talk) 21:18, 2 July 2021 (UTC)
- That is interesting, the normal story for asymmetric catalysis is that it came out of nowhere through the work of Noyori and Knowles in 1968. Somewhat related: paper was shown to work for chiral chromotography in 1952 doi:10.1039/JR9520003940 --Project Osprey (talk) 22:51, 2 July 2021 (UTC)
- Mostly I was just amused by it. The cheapest imaginable support combined with one of the most expensive metals - boldly solving problems no one knew existed. Unless there are any applications for the enantio-pure forms (asymmetric grignards?) then its very probably undue. I'll have a look next week, but I strongly suspect the answer will be no. --Project Osprey (talk) 22:42, 2 July 2021 (UTC)
- I've found a total of 2 papers where it's been used as a chiral solvent (doi:10.1021/ja300667y & doi:10.1016/j.tetlet.2009.08.060). That's not enough in my view so I'll remove the section but retain a note that it's racemic. Revert me if you feel otherwise. --Project Osprey (talk) 15:16, 7 July 2021 (UTC)
