Erich Clar page

[edit]

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.

Our Rangpur friend

[edit]

I saw you blocked a prbable LOUTSOCK of the person doing the disruptive page moves at Rangpur. Should this go to SPI if they do it again or would that be WP:QUACKing loud enough to skip that step? TornadoLGS (talk) 20:19, 19 December 2025 (UTC)[reply]

I'd say SPI if it happens again so we can keep a central record (plus more eyes means faster catching in the future). Looking at some deleted histories, I see an article-overlap with a much older sock-pile, but the material they each added seem different enough I think it's unrelated.

I'm a bit surprised the main account wasn't indeffed tbh. Or is it stale since the main account hasn't edited in a bit? TornadoLGS (talk) 22:23, 30 December 2025 (UTC)[reply]

Fluorescence and Photochemistry

[edit]

Dear Dmack, I noticed you reverted the categories for the Intrinsic DNA Fluorescence article. You mentioned that "photochemistry" is not simply the intersection of "anything chemistry" and "anything involving light." While I understand that distinction, I believe this specific category is highly appropriate here. Fluorescence is a fundamental pillar of photochemistry (as seen in any standard textbook on the subject). Furthermore, DNA fluorescence is a staple topic at international photochemistry conferences, and many of the references cited in the article are from dedicated photochemistry journals. Given that the scientific community treats this as a core part of the discipline, I think the category should be reinstated. Many thanks Serbacc (talk) 10:18, 26 December 2025 (UTC)[reply]

I don't see substantive article content to support that there is much "chemical" happening with the photo process, other than that it fluoresces. While it may have applications to chemistry, and obviously fluorescence is widely used in and benefits from chemistry, this article as it stands does not demonstrate that this specific topic does. The closest I see is the lead-section statement "contribute to understanding the very first steps of a complex series of events triggered by UV radiation, ultimately leading to DNA damage.". But that's too weak a connection to my eye (appears to be only using it as a reporter for the chemistry, not actually involved in the chemistry?). DMacks (talk) 15:47, 26 December 2025 (UTC)[reply]

And this is still happening. Not sure how to address it or if its even worth it. CNMall41 (talk) 04:22, 2 January 2026 (UTC)[reply]
