I want to include a synthetic reaction that is known as Clar's reaction. It is of a certain class of cyclic ketones that condense with themselves when heated to 400 C in a mixture of zinc dust and zinc chloride.
I will add references and a description of what it is used for in synthesizing new polycyclic aromatic hydrocarbons.
Thank you for deleting the file:Copper(I)-nitrate-3D-model.png. My name is Hoa112008. I know that the old file is incorrect and now the new file is more accurate. My account, the password is too easy, so someone other than me stole it to violate the policy, so it is natural to be locked. I understand, but that account doesn't work. Can you give me an Email address so I can send you the correct file so you can upload it again?
Can you teach me how to secure my account and get the admin to block the file renaming and category renaming functions to keep them from doing bad things?
Hoa112008, user IP adress.
You get this message because you are an admin on a Wikimedia wiki.
When someone s a Wikimedia wiki without being logged in today, we show their IP address. As you may already know, we will not be able to do this in the future. This is a decision by the Wikimedia Foundation Legal department, because norms and regulations for privacy online have changed.
Instead of the IP we will show a masked identity. You as an admin will still be able to access the IP. There will also be a new user right for those who need to see the full IPs of unregistered users to fight vandalism, harassment and spam without being admins. Patrollers will also see part of the IP even without this user right. We are also working on better tools to help.
We have two suggested ways this identity could work. We would appreciate your feedback on which way you think would work best for you and your wiki, now and in the future. You can let us know on the talk page. You can write in your language. The suggestions were posted in October and we will decide after 17 January.
Thank you. /Johan (WMF)

Differently than you, my IP address is public, and does not affect the fact you are contributing to vandalise a page with false information. — Preceding unsigned comment added by Otto-Christian von Bismarck (talk • contribs) 04:51, 11 January 2022 (UTC)
I'm a producer on a podcast and we are doing an episode about Encyclopedia Britannica and Wikipedia. I'm reaching out because I noticed you post a lot on the wiki page for errors in EB that have been corrected on Wikipedia. I have some more specific questions for you, could you reach out to me directly
Thanks in advance.
I understand why this was removed from Zwitterion, but the lability of the proton does not invalidate the example. It means that the two isomers will be in equilibrium in solution. I don't know why the zwitterion is shown in the article Psilocybin. Is this the form found in the solid state crystal structure or was it just assumed on the basis that the Me2N(R) group is more basic than the phosphate group? It was included on the basis of the structure shown in the article. Petergans (talk) 12:24, 17 January 2022 (UTC)
