Somehow this article should be reconciled with transfer hydrogenation
editPossibly this article could be converted to a more focused discussion of the Noyori-Shvo-etc catalysts, vs the catalysis. But catalytic transfer hydrogenation is not well developed in this encyclopedia. Also the present article has been filled with references that are both hyperspeciallized and lacking titles, which makes them even less useful. --Smokefoot (talk) 13:23, 31 July 2008 (UTC)
- Very good, I looked up Wikipedia:Citing_sources/example_style and I see that titles are expected and will include them from now on. As for the citation specialization the subject is rather specialized so it seemed appropriate but it will be worth finding a few review articles to support the papers listed. I have no position on the current state of transfer hydrogenation. In this page I think the distinction between catalyst and catalysis is clear. I would imagine that further description and images of Shvo's, Casey's (Fe system), and at least one of Noyori's many systems would be useful. I think anyone who has an opportunity to add that material should. I think its also worth noting that the term bifunctional catalyst is used beyond the realm of hydrogenation. I don't have as much experience in the area but I have read papers and seen biological presentations in which they describe active sites as bifunctional. Even if bifunctional catalysts were associated with only transfer hydrogenation it would be worth having a page on the subject(catalyst) as well as the action(catalysis).--OMCV (talk) 14:12, 31 July 2008 (UTC)
- For the hydrogenation part, I wonder if the cited articles are (i) too specialized and (ii) even appropriate. It almost seems that the definition is developed to encompas a few (mainly US) authors. Ionic hydrogenation is probably a separate topic, a highly specialized subset of heterolytic activation. Shvo's is a transfer hydrogenation catalyst. The article probably would benefit from brief definition of scope. Noyori coined the term binfunctional catalysts and mechanism (Noyori JOC 2001, 7931 and Phil. Trans. R. Soc. A 2005, 901–912). In that usage, bifunctional refers to the pericyclic pathway for transferring H2 to ketones and imines. The other material should probably be moved (to Transfer hydrogenation or removed.--Smokefoot (talk) 19:44, 25 April 2010 (UTC)
- A couple years can make a difference. I think you are right about most issues except for the intent to develop a US centric perspective, if that exists its unintentional. I started this page when I was interested in producing content. Over that period some of the content I produced was better than others. In this situation I stretched the definition beyond the intent of the classical definition. I'll look at pulling inappropriate content.--OMCV (talk) 03:38, 26 April 2010 (UTC)
- After looking it over I was clearly being way to creative with my definition. I wish I had time to write something that did the subject (and Nayori) justice but at the time I don't. If you wanted to push for a deletion or just convert this page into a redirect I would not oppose you.--OMCV (talk) 03:55, 26 April 2010 (UTC)
