Talk:Ketenyl anion

General[edit]

Would be good to read over and fix minor spelling, grammar errors Ephineprine (talk) 17:23, 18 December 2023 (UTC)[reply]

Lead[edit]

Peer review comments Ephineprine (talk) 16:09, 18 December 2023 (UTC)[reply]

"However, it has a negative charge on terminal carbon and oxygen atom" - it has a negative charge on both? Would it be a dianion in this case? Ephineprine (talk) 16:17, 18 December 2023 (UTC)[reply]

I was about to say that there is negative charge on either carbon atom or oxygen atom because of resonance structure. I rephrased it for clarity. Hienn211 (talk) 19:12, 18 December 2023 (UTC)[reply]

"Its resonance structures illustrate major electronic structure." - Would you explain a bit more about what major electronic structure means? Ephineprine (talk) 16:18, 18 December 2023 (UTC)[reply]

I removed this sentence and added more details on previous sentence to discuss more about resonance structure. I realized that this sentence does not connect with previous sentence fluently. Hienn211 (talk) 19:16, 18 December 2023 (UTC)[reply]

In the lead section, "it has a negative charge on either terminal carbon and oxygen atom" is confusing. Seems like the connecting word should be "or" instead of "and". OneMustImagineAGradStudentHappy (talk) 06:42, 19 December 2023 (UTC)[reply]

Thank you the catch Hienn211 (talk) 14:43, 19 December 2023 (UTC)[reply]

Synthesis[edit]

"Later in their studies, the ketenyl anion product upon carbonylation can be selective by chanhging electron-withdrawing ability on a certain leaving group and Lewis acidity of coordinated alkali metal cation" - Would be good to be more specific on the leaving group and alkali metal, and what changes are induced respectively Ephineprine (talk) 16:49, 18 December 2023 (UTC)[reply]

I added more details on trend of leaving group and Lewis acidity on alkali metal cation in selective carbonylation reactions. Hienn211 (talk) 21:20, 18 December 2023 (UTC)[reply]

Minor typo - changhing Ephineprine (talk) 16:25, 18 December 2023 (UTC)[reply]

fixed it! Hienn211 (talk) 19:20, 18 December 2023 (UTC)[reply]

In the synthesis section, toward the end of the first paragraph, did you mean triphenylphosphine instead of "tryphenylphosphine"? OneMustImagineAGradStudentHappy (talk) 06:44, 19 December 2023 (UTC)[reply]

I fixed it Hienn211 (talk) 14:43, 19 December 2023 (UTC)[reply]

Structure[edit]

Citation for first paragraph would be good Ephineprine (talk) 17:15, 18 December 2023 (UTC)[reply]

I added an appropriate reference for describing resonance structure. Hienn211 (talk) 03:26, 19 December 2023 (UTC)[reply]

"Inoue's silca-ketenyl anion product, shown in Figure 2, had Wiberg bond index of 1.68 and 1.76 for Si-C bond and C-O bond, respectively." - What is the signficance of this? Ephineprine (talk) 17:12, 18 December 2023 (UTC)[reply]

I was intended to explain that bond indices demonstrates Si=C=O structure, which resembles ketenyl anion structure. I added an sentence to explain the meaning of the bond indices in this particular examples. Hienn211 (talk) 03:35, 19 December 2023 (UTC)[reply]

In the structure section, in the second paragraph, I believe Inoue's "silica-ketenyl" should contain an "i" in silica. OneMustImagineAGradStudentHappy (talk) 06:45, 19 December 2023 (UTC)[reply]

fixed it Hienn211 (talk) 14:45, 19 December 2023 (UTC)[reply]

In Figure 4, the center nitrogen atom in the first compound seems to have 10 electrons in its shell. Is that possible? OneMustImagineAGradStudentHappy (talk) 06:46, 19 December 2023 (UTC)[reply]

It has to be 8 electrons. I fixed the structure of the compound. Hienn211 (talk) 14:52, 19 December 2023 (UTC)[reply]

Reactivity[edit]

Peer review comments Ephineprine (talk) 16:10, 18 December 2023 (UTC)[reply]

"Not only at the central carbon, the carbon atom between central carbon and oxygen atom can also be functionalized upon electrophilic substitution." - Is there a term for this carbon? To enhance understanding Ephineprine (talk) 17:23, 18 December 2023 (UTC)[reply]

I did not find proper term to describe a specific carbon in ketene functional group. I revised this sentence to specify which carbon I discussed. It would be great if there is a appropriate or proper term describing a specific carbon in ketene. Hienn211 (talk) 03:45, 19 December 2023 (UTC)[reply]

"These products requires CO and substrates of interests, which highlight new synthetic pathways of organic compounds without extreme conditions." Under what conditions are these reactions run? Ephineprine (talk) 17:23, 18 December 2023 (UTC)[reply]

They run at room temperature. I added more description on this sentence. Hienn211 (talk) 04:00, 19 December 2023 (UTC)[reply]

Citation for this paragraph - I think it should be Gessner (4) - would be good Ephineprine (talk) 17:23, 18 December 2023 (UTC)[reply]

Added it! Hienn211 (talk) 04:01, 19 December 2023 (UTC)[reply]
