Talk:Organosilicon chemistry

Toxic?

Organic Silicon compounds seem to be all the rage in the CAM scene, esp in France. Does anybody here have links/data/info on toxicological or pharmaceutical effects of such compounds? Googling just yields quack results for me. --Krazykraut2011 (talk) —Preceding undated comment added 17:44, 25 June 2013 (UTC)

Silanols

Would anyone like to add more discussion of silanols and silanediols in the article?

These seem like important precursors to the ubiquitous siloxanes.

Not in any biomolecule?

The article claims that "Carbon-silicon bonds are not found in any biomolecule". I have seen a claim that an organosilicon compound was detected by NMR in an alga. The ref I have is "Dalton Transactions, Christopher T.G. Knight" but I access the paper at the moment. Is is confirmed? --Jorge Stolfi (talk) 20:33, 1 July 2009 (UTC)

I got the paper. It interprets the data as silicon in hexavalent coordination, possibly interactig with a nitrogen atom. --Jorge Stolfi (talk) 20:59, 1 July 2009 (UTC)

Sila-substituted medicines

There is a classical group of experimental drugs that incorporate silicon. They replace one or more carbon atoms in a known drug with a silicon atom. The results are drugs with modified properties. Sila-substituted medicines need to be mentioned. GreySun (talk) 21:55, 22 November 2009 (UTC)

You are correct that this theme is popular, but I do not think that any organoSi compounds are medically important ... yet. There are some pesticides though. --Smokefoot (talk) 19:35, 25 June 2013 (UTC)

bond energies

As far as I know, the bond dissociation energies given in the chapter "properties of Si-C, Si-O and Si-F bonds" are all too high. A C-O single bond has some 350 (not 538) kJ/mol, a C-C single bond is also around 350 rather than 600 kJ/mol, and the 800 kJ/mol given for the Si-O bond is too much for a single covalent bond (800 kJ/mol is already close to a triple bond). Furthermore, the given values are not cited (or have I overlooked a citation?).

For the C-C and C-O bond, see also bond dissociation energy. I don't know the exact dissociation energies of (silicon-other element) bonds, and they are rather hard to find in the literature since they are not part of most organic chemicals (compared to C-C, C-H, C-O, C=O, C-Cl and so), but the values this article gives are improbably high. --79.243.225.236 (talk) 16:54, 14 September 2014 (UTC)

 Done I think that this serious problem has finally been dealt with. --Smokefoot (talk) 22:16, 27 January 2023 (UTC)

Starting off wrong?

"Organosilicon compounds are organometallic compounds"?!? — Preceding unsigned comment added by 174.100.201.44 (talk) 15:50, 17 July 2020 (UTC)

Carbosilanes & Silanes

@V8rik and Smokefoot: Hi. Why don't we link Category:Carbosilanes & Silanes into this article? AXONOV (talk) ⚑ 19:32, 4 January 2023 (UTC)

That category is bad and should be removed or corrected. Carbosilanes have Si-C-Si bonds. See the book "Carbosilanes Syntheses and Reactions" by Fritz and Matern.--Smokefoot (talk) 19:51, 4 January 2023 (UTC)
