Erich Clar page

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.

Tech News: 2026-22

Latest tech news from the Wikimedia technical community. Please tell other users about these changes. Not all changes will affect you. Translations are available.

Weekly highlight

Following a successful account creation experiment, an improved logged-out edit warning message will be deployed to all Wikimedia wikis in the first week of June. The change will only affect logged-out users on mobile web who open an editing session. The updated experience is designed to encourage account creation more clearly, while still allowing users to edit with temporary accounts. Results from the experiment showed a significant increase in account creation, with a 27% relative lift among users shown the updated message. As expected, as more people funnel into account creation, temporary accounts decreased by a relative 16%. The experiment did not show any significant changes in constructive edit rates or other monitored contributor metrics. [1]

Updates for editors

For security reasons, members of certain user groups are required to have two-factor authentication (2FA) enabled. Members of these groups will be unable to disable the last 2FA method on their account, and it will be impossible to add users without 2FA to these groups. Users will still be able to add new authentication methods or remove them, as long as at least one method is continuously enabled. In the next few weeks, users without 2FA will be removed from these groups. Notably, this applies to bureaucrats. See the linked tasks for deployment schedules. [2][3]
WMDE Technical Wishes will run an A/B test on 10 wikis, testing potential improvements for Reference Previews. The experiment will run for ~2 weeks at the end of May / beginning of June and will affect 10% of desktop readers on the participating wikis.
After two successful experiments, the Reader Growth team is rolling out an Image Browsing beta feature for all Wikipedias on mobile on May 25. This means that anyone who has all beta features on by default will start to see this feature, and others can check the box to turn it on in their preferences. The beta feature will include a carousel of all an article's images at the top of the article, with controls for editors to exclude images from the article's carousel or to exclude an article from the feature entirely.
View all 30 community-submitted tasks that were resolved last week. For example, three dimensional STL files were being rendered incorrectly by the media viewer 3D extension which is now fixed. [4]

Updates for technical contributors

The legacy CSS classes tleft and tright have been replaced with floatleft and floatright as the former do not work consistently across all MediaWiki platforms, notably mobile web and mobile apps. Projects relying on these classes are encouraged to review related usage and plan for migration. Please note that floatleft and floatright may also be deprecated in future, although there are currently no plans to do so. Read more.

Move a page

Hi! I'm here because I can't move a page from my user space to the main space. Could you please tell me what I should do, or would it be possible for you to move it for me? User:Harminon2/Doc (TV series 2026) Harminon2 (talk) 02:11, 29 May 2026 (UTC)[reply]

Hi User:Harminon2. I do not know enough about the standards for TV series to recognize whether this meets the notability requirement and I cannot read Spanish to look at the refs to help me. It might be better to go through the usual "Article for Creation"/draft queue. Edit your article to place the following line at the very top:

After you save that edit, your article should now have a box with instructions, ending with a blue "Submit the draft for review!" button. Clicking that will place your article in the queue where a reviewer who feels comfortable with this topic-area will handle it. DMacks (talk) 02:24, 29 May 2026 (UTC)[reply]

Advice on Black British People page

Hi, I'm quite new, so apologies for any mistakes I make in editing. I definitely didn't mean for my edit to be less than neutral. The recommended edits section lists some tasks as removing promotional material, which is why I put that for my edit, though I think "Tone Revision" would be more accurate in this case, and I should have done that or something else.

I would like to know your thoughts on the content of the edit, as I intended to make the text more aligned with the source which it references. The source material says "Nigerian pupils are achieving above the average for all Black African pupils, and above the average for all pupils" which I thought didn't match what was written, as from what I could tell, "Black Nigerian" pupils are only compared to "Black African (national figure)" and "All pupils (national figure)" and not to white pupils. That said, I do think that my edit could have been worded better, but I think that comparing to white pupils is making a conclusion not in the source.

Thanks for the help, I'm looking to improve my editing! Kay6067 (talk) 02:52, 1 June 2026 (UTC)[reply]
