No house points. It's organic chemistry! The article is about Doyle's recent Nature on phosphaphotoredox hydroamination. Don't get me wrong, this is an -awesome- paper... I'm just not sure the headline is a perfect match. And the article ends with this quip, suggesting... confusion😂 #chemchat

Introduction Post!
I'm an Organic Chemistry Prof, living in Alberta. Fatigued by fascism in general, and by the UCP in particular, but I find occasional reprieve in Science Fiction and Fantasy fandom.
I enjoy this weird, leftist social media, with no algorithm or ads.

My mom spent the whole day with me while I cleaned the Organic Chemistry lab. Also some important chemicals came in.
I know I keep promising this but I'm getting very close to being able to demonstrate to everyone the semisynthesis of CBD to THC!

I took my first degree in the Natural Sciences Tripos at the University of Cambridge. This involved doing a very general first year comprising four different elements that could be chosen flexibly. I quickly settled on Physics, Chemistry and Mathematics for Natural Sciences to reflect my A-level results but was struggling for the fourth. In the end I picked the one that seemed most like Physics, a course called Crystalline Materials. I didn’t like that at all, and wish I’d done some Biology instead – Biology of Cells and Biology of Organisms were both options – or even Geology, but I stuck with it for the first year.
Having to do such a wide range of subjects was very challenging. The timetable was densely packed and the pace was considerable. In the second year, however, I was able to focus on Mathematics and Physics and although it was still intense it was a bit more focussed. I ended up doing Theoretical Physics in my final year, including a theory project.
My best teacher at School, Dr Geoeff Swinden, was a chemist (he had a doctorate in organic chemistry from Oxford University) and when I went to Cambridge I fully expected to specialisze in Chemistry rather than Physics. I loved the curly arrows and all that. But two things changed. One was that I found the Physics content of the first year far more interesting – and the lecturers and tutors far more inspiring – than Chemistry, and the other was that my considerable ineptitude at practical work made me doubt that I had a future in a chemistry laboratory. And so it came to pass that I switched allegiance to Physics, a decision I am very glad I made.
(It was only towards the end of my degree that I started to take Astrophysics seriously as a possible specialism, but that’s another story…)
Anyway, when I turned up at Cambridge over 40 years ago to begin my course, and having Chemistry as a probable end point, I bought all the recommended text books, one of which was Physical Chemistry by P.W. Atkins. I found a picture (above) of the 1982 edition which may well be the one I bought (although I vaguely remember the one I had being in paperback). I thought it was a very good book, and it has gone into many subsequent editions. I also found the Physical part of Chemistry quite straightforward because it is basically Physics. I even got higher marks in Chemistry in the first year than I did in Physics but that didn’t alter my decision to drop Chemistry after the first year. When I did so, I followed tradition and sold my copy to a new undergraduate along with the other books relating to courses that I dropped.
Yesterday I found out that Peter Atkins has decided to make one of his books available to download. The book concerned is however not the compendious tome I bought, but a shorter summary called Concepts in Physical Chemistry, which was published in 1995. This is no doubt a very useful text for beginning Chemistry students so I thought I’d pass on this information. You can download it here, although you have to do it chapter by chapter in PDF files.
P.S. Chemistry in Spanish is ‘Química’. Since Physics and Chemistry share the same building in the University of Barcelona, where I am currently working, I frequently walk past rooms with doors marked ‘Quim’ (but I have never taken the opportunity to enter one).

CH3+ reacts with a wide range of other molecules and has been theorized to be the cornerstone of interstellar organic chemistry, yet until now has remained undetected.
The discovery vindicates the theory that CH3+ can form in the presence of strong UV radiation. UV radiation is destructive to complex organic molecules, but under the right conditions it can facilitate it. There is evidence that the solar system disk was UV radiated by a nearby star. -

I am a Trinitarian, if not exactly a good Catholic, so I like to find threes of things. Once you're alert to the ubiquity of three-fold equilibria among fundamental concepts, it's hard not to start seeing triangles in everything…Jewish art and architecture is really good at evoking triplets of things, isn't it? Marvellous. I think of crystals and pyramids and sequences of numbers and all sorts of fun things, when I glance towards the Tree of Life. Kabbalah is closed to me but…c'mon, look at it! of COURSE it's powerful! It's like higher mathematics (cf. the intricate radial and cylindrical symmetries of Muslim art and architecture and its spectacular knowledge of tesselations.)
There is a holy trinity of goat acids. I do not lie! One can speak sensibly, in chemistry, of the goat acids. There are three medium-chain fatty acids, three 'normal' (i.e. straight-chain) alkanoic acids, that are the goat acids.
Caproic acid, hexanoic acid, CH3(CH2)4COOH
Caprylic acid, octanoic acid, CH3(CH2)6COOH
Capric acid, decanoic acid, CH3(CH2)8COOHAll of them have a name which refers to the goat as seen below. The Latin word for goat is capra (and caprea and capriolus and some others, Latin is a bit loosier-goosier with alternate spellings and word-forms than English) and thus supplies the root for all these chemical names. And all these acids and certain compounds of these acids are especially commonplace in goats. Cute widdle bouncy gotes which my esteemed colleague Kaylin Evergreen detests. She is (to me anyway) a priestess of Queen Hera, the formidable matriarch of the Hellenic deities whom I honor as best I can, in whose guidance I have trusted in many lean times and bitter moments. Hera bears among other epithets the name of Ἥρη Αἰγοφάγος, Goat-Eating Hera! Hence I am always getting a bit of stink-eye from Queen Hera about my own…dalliances with gotes. In the past, as it were. oh dear
Anyway! I have had a long-time fascination with this little chemical triplet, which I once remember seeing pop up in a diagram showing how those three acids could be resolved on a liquid chromatographic column. They're "model compounds" indeed: showing that you can resolve the three acids cleanly with your analytical equipment is a good demonstration of the effectiveness of chemical analysis.
They're found among many living things, not just goats; they're among the common lipids of organic life on Earth. Valerian root is another material that tends to be rich in the goat acids and thus valerian has a characteristic stench about it. I happen to regard it as a more or less pleasant smell in moderation (I guess I would) but I will allow as how it's a bit overpowering of other smells. They're just a bit more volatile than other organic acids likely to be found, so…you smell them more.

The term biochar had not been coined back then, but I wish the experiments outlined in Liebig's 1840 book 'Organic Chemistry in its Application to Agriculture and Physiology' would have generated greater interest starting back in the 19th century. #CDR dn711509.ca.archive.org/0/items/orga...

The Juxtaposition of Light
These tiny insects create light through a chemical reaction involving luciferin and oxygen. It is nearly 100% efficient light, meaning almost no energy is lost as heat. It’s a miracle of organic chemistry occurring right at our feet.

#Maine Is a Warning for America’s #PFAS Future
Story by Zoë Schlanger
4/11/2024"Cordelia Saunders remembers 2021, the year she and her husband, Nathan, found out that they’d likely been drinking tainted water for more than 30 years. A neighbor’s 20 peach trees had finally matured that summer, and perfect-looking peaches hung from their branches. Cordelia watched the fruit drop to the ground and rot: Her neighbor didn’t dare eat it.
"The Saunderses’ home, in Fairfield, Maine, is in a quiet, secluded spot, 50 minutes from the drama of the rocky coast and an hour and 15 minutes from the best skiing around. It’s also sitting atop a plume of poison.
"For decades, sewage sludge was spread on the corn fields surrounding their house, and on hundreds of other fields across the state. That sludge is suspected to have been tainted with PFAS, a group of man-made compounds that cause a litany of ailments, including kidney and prostate cancers, fertility loss, and developmental disorders. The Saunderses’ property is on one of the most contaminated roads in a state just waking up to the extent of an invisible crisis.
Onur Apul, an environmental engineer at the University of Maine and the head of its initiative to study PFAS solutions, told me that in his opinion, the United States has seen 'nothing as overwhelming, and nothing as universal' as the PFAS crisis. Even the #DDT crisis of the 1960s doesn’t compare, he said: DDT was used only as an insecticide and could be banned by banning that single use. PFAS are used in hundreds of products across industries and consumer sectors. Their nearly 15,000 variations can help make pans nonstick, hiking clothes and plumber’s tape waterproof, and dental floss slippery. They’re in performance fabrics on couches, waterproof mascara, tennis rackets, ski wax. Destroying them demands massive inputs of energy: Their fluorine-carbon bond is the single most stable bond in organic chemistry."
