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.
Every once in a while I notice the gears of the Wikipedia machine being turned around and I'm impressed by the social organization of it. Because it is not a mindless machine, but flawed, wonderful, thinking people doing their best. People paying attention, making notes, being part of the solution to problems (and not the precipitate as the Chemistry joke goes). Sure, people come in trying to turn over the tables, but just as quickly other people are cleaning it up and putting everything back where it was, or even maybe a bit cleaner than it was before the fracas. I checked back on a little vandalism thing and saw your notes on sock investigations. You and Classicwiki making sure the boxes get checked and it made me impressed with how well our little place works. Thanks for being part of it. 🌿MtBotany (talk) 05:27, 2 May 2024 (UTC)
