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.
Hi MPGuy2824. Thanks for the note (and NPP in general!). Unfortunately, the reviewer-scripts are often confused by multiple editors and by redirects, with a side helping of LTA. DMacks (talk) 14:12, 30 August 2025 (UTC)[reply]

The Editing team wants to compile a list of templates, jargon terms, and policies used in edit summaries when a copyright violation is removed. This will help them identify the number of edits reverted due to copyright issues. We invite community members from the following Wikis to list these terms in T402601, or to share their list with Trizek_(WMF): Arabic Wikipedia, Czech Wikipedia, German Wikipedia, English Wikipedia, Spanish Wikipedia, Persian Wikipedia, French Wikipedia, Hebrew Wikipedia, Indonesian Wikipedia, Italian Wikipedia, Japanese Wikipedia, Korean Wikipedia, Dutch Wikipedia, Polish Wikipedia, Portuguese Wikipedia, Turkish Wikipedia, Ukrainian Wikipedia, Vietnamese Wikipedia, Chinese Wikipedia. This project is open until September 9th 2025.
Updates for editors
The CampaignEvents extension has been enabled for all Wikisources. The extension makes it easier to organize and participate in collaborative activities, like edit-a-thons and WikiProjects, on the wikis. The extension has three features: Event Registration, Collaboration List, and Invitation List. To request the extension for your wiki, visit the Deployment information page. [1]
The lists in the footer of the editing interface, such as "Templates used on this page," will now be organized into columns when there is enough space. This enhancement minimizes scrolling when editing lengthy articles on Wikipedia. [2]
On September 3rd, 2025 we will increase the sampling percentages of our group by toggle experiment of the Special:RecentChanges, Special:Watchlist, and Special:RelatedChanges pages on the Chinese, French, and Portuguese Wikipedias to 100 percent, allowing more editors to be part of this experiment. This adjustment is intended to ensure we have sufficient data to make informed decisions when evaluating the experiment results. [3][4]
Upon clicking an empty search bar, logged-out users will see suggestions of articles for further reading on English Wikipedia beginning the week of September 22. The feature will be available on both desktop and mobile. All non-English wikis received this change in June and July. The goal is to make it easier for users to find articles. Learn more.
Wikifunctions now has a new capability called "lightweight enumeration types", an enumeration type is simply a fixed set of values that's in the type's definition. This capability makes it quick and easy to define such a type, and allows for the reuse of values that are already present in Wikidata. Here is a newsletter to learn more.
The latest Readers Newsletter is now available. This edition includes: the formation of two new teams — Reader Growth and Reader Experience; insights into declining pageviews and account creations; highlights from the Wikimania Nairobi panel on improving the reading experience; upcoming experiments to engage new and existing readers; and more.
An RfC is open on whether use of emojis with no encyclopedic value in mainspace and draftspace (e.g., at the start of paragraphs or in place of bullet points) should be added as a criterion under G15.
An RfC is in progress to amend the structure, rules, and procedures of the Arbitration Committee election and resolve any issues not covered by existing rules.

The Editing team is working on a new check: Paste check. This check informs newcomers who paste text into Wikipedia that the content might not be accepted. This check is an effort to increase the likelihood that the new content people are adding to Wikipedia is aligned with the Movement's commitment to offering information under a free content license. This check will soon be tested at a few wikis. If your community is interested in this test, please tell us in this task, or contact the team.
When browsing a wiki (like en.wikipedia.org), the software responds in one of two ways: a desktop page, or a redirect to a mobile version on an "m" domain (like en.m.wikipedia.org). Over the next three weeks, MediaWiki will start displaying the mobile version to mobile devices directly on the standard domain, without this redirect. This change does not affect existing m-dot URLs, or the "Desktop view" opt-out. Learn more. [7]
When an edit changes the categories of a page, the changes to the category membership counts are now happening asynchronously. This improves the speed of saving edits, especially when moving many pages to or from the same category, and reduces the risk of site outages, but it means that the counts can show outdated information for a few minutes. [8]
Edits on Wikidata to qualifiers (properties and values) and references (properties and values) in a Wikidata item statement will now not add entries to the RecentChanges or Watchlist pages on all other Wikis. This is a temporary change to improve performance while other solutions are created. Wikidata's own pages remain unchanged. Learn more. [9][10]
Japanese-language wikis have had a major upgrade to the way that search works. The new search should generally give more accurate and more relevant search results. [11]
