Talk:Pentamethylcyclopentadiene

Introducing

Might it be worth to make something like a page on the cyclopentadienyl-LIGAND, and giving the organic molecule 1,2,3,4,5-Pentamethylcyclopentadiene his own page as the organic molecule. --Dirk Beetstra 07:31, 3 May 2006 (UTC)[reply]

Alternatively have this page be the free ligand and have a chart of links to its complexes. In any case the current article is tiny now and in some glorious future we should probably break it down just like you say. I havent looked at CpH article. Also note that the prep described for Cp*H is not the popular one that starts from acetaldehyde and gives on 100's of mL of the stuff- the prep in Inorg Syntheses. My student just ran out of energy and chemical knowledge, but this is the key prep. Also I dont think that the article explains the fundamental fact that unlike CpH, Cp*H is not a dienophile, or at least it does not self-dimerize. And probably the "cone angle" of Cp* must have been analyzed by someone. If you are a V enthusiast you will notice that Teuben's work is not cited.--Smokefoot 14:04, 3 May 2006 (UTC)[reply]

You may never guess again where my ETM enthousiasm is founded ...

I indeed noticed the missing synthesis via the cyclopentenone. The problem is mainly, that it is not Cp* alone, also the constrained geometry catalyst uses a Cp with substitution, and the differences with (C5Me4R)^- etc, so probably I will rewrite CpH and Cp*H both towards an organic page (leave the organics to the organic chemists, only stating the obvious), and start a 'cyclopentadienyl' page, where I will try to collect some CpM-chemistry. --Dirk Beetstra 17:04, 3 May 2006 (UTC)[reply]

Splitting of the diene and dienyl

I have moved all information pertaining "cyclopentadienyl" (as the ligand used in organometallic chemistry) to Cyclopentadienyl complex. I suggest that this page evolves further as a description of the organic molecule, describing

physical properties,
it's synthesis,
reactivity
acidity (this can be linked with the page Cyclopentadiene)

The page 'cyclopentadienyl' now redirects to 'cyclopentadienyl complex' It might be worth to describe also the Cp* analogues like 1,2,3,4-tetramethylcyclopentadiene, etc.--Dirk Beetstra 20:32, 3 May 2006 (UTC)[reply]

References

Shouldn't be the references under the chapter references and not in the "text-block"? --Minihaa (talk) 19:58, 28 December 2012 (UTC)[reply]

Thanks for the suggestion, which was dealt with. --Smokefoot (talk) 22:13, 28 December 2012 (UTC)[reply]
