message: "Complexes of PF3 often parallel those of the metal carbonyls."
Does it mean the Complexes of PF3 is similiar to metal carbonyls? I would like to know the meaning. Thanks a lot.--Wolfch (talk) 13:48, 19 August 2010 (UTC)
thread_title:  What does this mean? 

message: Hi Smokefoot, I thought that the history section gives a more generally understandable access to the topic, at least for non-chemists; this is why I put it to the top. Furthermore I believe that the Isolobal principle allows a better understanding of some metal carbonyl structures. I think it should be mentioned somewhere in the article (ok, may be not in the synthesis section). -- Linksfuss (talk) 13:36, 1 May 2012 (UTC)
replies: text: Usually our articles focus on the basic observables (structures, formulas, syntheses, apps) before discussing theoretical aspects, at least at length. That arrangement is my understanding, and I think it is a good idea.  I will suggest this on a talk page of our Manual of Style and see what others think. Thanks for noticing.--Smokefoot (talk) 12:50, 17 May 2012 (UTC)

message: Hi Smokefoot, Wolfgang A. Herrmann called this in a review article about metal carbonyls (W. A. Herrmann: 100 Jahre Metallcarbonyle. In: Chemie in unserer Zeit. 1988, 22. Jahrg., Nr. 4, ISSN 0009-2851, pp. 113–122) a "legendary reaction discovered by Reppe" (W. Reppe, 0. Schlichting, K. Klager and T. Toepel. Cyclisierende Polymesrisation des Acetylens. In: Justus Liebigs Ann. Chem. 560, 1 (1948).) -- Linksfuss (talk) 09:38, 17 May 2012 (UTC)
replies: text: Trimerization is a legendary reaction.  But it is not useful and definitely not an application.   I am almost certain that the tetramerization to COT is also not used for anything except to supply researchers.  Also, according to our article cyclooctatetraene, it is more commonly prepared by non carbonyl routes.  Looking forward to your future edits.--Smokefoot (talk) 12:28, 17 May 2012 (UTC)
replies: text: Just checked my favorite source on industrial routes for the synthesis of substituted pyridines from alkynes and nitriles.  Ullmann's Encyclopedia of Industrial Chemistry indicates that it is used, but the catalyst is CpCo(cod), which also fits my recollection.  There is a review by Boennemann (MPI-Muelheim) in ACIE many years ago on this theme if you want to dig forward in time (DOI: 10.1002/anie.197805051).--Smokefoot (talk) 12:50, 17 May 2012 (UTC)

message: Concerning the correct labeling of the MO scheme (only the valence electrons shown):
The 4sigma label of the highest MO should be exchanged by 6sigma  — Preceding unsigned comment added by 2A02:120B:2C7E:71D0:9CF6:5400:4E09:9B7E (talk) 17:43, 29 May 2015 (UTC)

New research has resulted in successful syntheses of Ca, Sr and Ba carbonyls that utilise d orbitals in defiance of common main group theory. I think this is notable enough to include in the page. However, it's not my area of expertise so I would like to defer to a specialist to explain it properly.

replies: text: thousands of publications appear annually on metal carbonyls.  They are suitably incorporated into review articles.  Wikipedia does not compete with Chem. Rev. and other technical review journals per WP:SECONDARY.--Smokefoot (talk) 17:27, 31 August 2018 (UTC)
thread_title:  Group 2 Carbonyls 

message: The article currently says "As part of their experiments the group treated nickel with carbon monoxide." ("They" includes Ludwig Mond.)  But I have read, in several places, that what happened was they were studying marsh-gas (a mixture of gases which includes carbon monoxide) in a vacuum chamber which had joinings made of nickel in its interior, and Mond noticed that those nickel parts were being eroded faster than normally, when marsh gas was used, and that is what prompted him to investigate further.   I'm too tired right now to find a source, but I'm just mentioning it on the TALK page. HandsomeMrToad (talk) 08:29, 13 March 2021 (UTC)
