A reaction scheme showing the direct alkoxycarbonylation of arenes using a dual ligand-based catalyst system.

A direct synthesis of versatile active esters! Massive congratulations to Simon Kaltenberger, Joshua Meinshausen, @jyotirmoydey.bsky.social and Celia Sanchez-Gonzalez on the development of a widely applicable sterically controlled alkoxycarbonylation of arenes now in JACS Au doi.org/10.1021/jacs...

Exttemely proud of this computational and experimental mechanistic work headed by @chimicafritz.bsky.social and supported by @monikaravi.bsky.social just out in @angewandtechemie.bsky.social

A reaction scheme showing a generic arene structure, which is first olefinated through a nondirected C-H olefination, followed by two oxidative cleavage pathways, one giving carboxylation products the other giving formylation products.

Access SEAr-type products in typically disfavored positions! Contratulatons to Rita, @jyotirmoydey.bsky.social and Elisa showin in Org. Lett. how nondirected C-H activation and oxidative cleavage can be used to obtain challenging regioisomers in formylation and carboxylation doi.org/10.1021/acs....

A simple, scalable method by Jurk & van Gemmeren @vangemmerenlab.bsky.social to convert secondary sulfonamides into sulfonyl fluorides using affordable #DAST ⚗️, yielding excellent results! These sulfonyl fluorides readily couple with amines to create diverse libraries.

Thank you for featuring our work. It was indeed a great experience to publish with you!

Synthesis of γ-alkylidene lactones via molecular stitching of carboxylic acids and olefins In this study, we describe a direct palladium-catalyzed tandem β-C(sp3)–H olefination/lactonization strategy for the one-step synthesis of γ-alkylidene lactones. The reaction is enabled by an N-acyl s...

The final version of our @vangemmerenlab.bsky.social
'Molecular Stitching' approach, enabling one-step access to a diverse library of γ-alkylidene lactones, is now out in @chemicalscience.rsc.org

Table of contents graphic showing the reaction of an aliphatic carboxylic acid with a styrene to give a γ-vinylidene lactone via tripple C-H functionalization. The structure of the ligand used is given as well as bullet points showing the main strenghts of the report, such as a broad substrate scope.

Great job Edis and @sourjyamal.bsky.social! Their work on the synthesis of γ-Alkylidene Lactones has just been accepted for publication in the @rsc.org journal @chemicalscience.rsc.org
doi.org/10.1039/D5SC...

Just saw on the OL homepage that the article currently leads the journals most read list, thanks for all the interest in our work! pubs.acs.org/action/showM...

Check out my latest preprint from @vangemmerenlab.bsky.social , where we disclosed a one-step approach to access γ-alkylidene lactones by stitching together aliphatic acids and styrenes, enabled by N-Acyl Sulfonamide ligand. doi.org/10.26434/che...

A screebshot from the ACS Catalysis homepage shiwing the article in the most read list.

Thanks for all the interest in the study. It is now amongst the currently most read in ACS Catalysis

Thank you Fritz!

Smashing distal C–H bonds of the unprecedented β-non-quaternary acids has been a formidable task over the years; several years of our involvement in 'Ligand Design' finally broke the deadlock! Thanks to @vangemmerenlab.bsky.social for guiding us to achieve this feat !

We have developed a direct gamma-lactonization of carboxylic acids. The scope includes beta-non-quaternary subatrates that were until now out of reach for carboxylic acid gamma-C-H activation. Congratulations to Tianxiao and Sourjya. Have a look at the study now posted on ChemRXiv t.co/Wu0XtwsEQR

Pd-catalysed direct β-C(sp3)–H fluorination of aliphatic carboxylic acids - Nature Synthesis C–F bond formation using transition-metal catalysis is a challenge owing to the high energy barrier associated with reductive elimination. Now the direct β-C(sp3)–H fluorination of aliphatic carboxyli...

Our work on the direct fluorination of carboxylic acids has just appeared in @NatureSynthesis! (www.nature.com/articles/s44...). This terrific study bySourjya Mal, Friedrich Jurk, and Kerstin Hiesinger is highlighted in a press release by our University:
