Check out this excellent review by @sourjyamal.bsky.social on carboxylic acid directed C(sp³)–H functionalization, covering distinct mechanistic strategies (C–H activation, HAT, etc), catalyst design principles, and their applications in building complex molecules. doi.org/10.1021/acs....

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 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.

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...
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.

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
