Ruthenium-catalyzed C–H activation of thioxanthones [PDF]

open access: yesBeilstein Journal of Organic Chemistry, 2015
Thioxanthones – being readily available in one step from thiosalicylic acid and arenes – were used in ruthenium-catalyzed C–H-activation reaction to produce 1-mono- or 1,8-disubstituted thioxanthones in good to excellent yields.

C–H Activation: Toward Sustainability and Applications [PDF]

open access: yesACS Central Science, 2021
Since the definition of the "12 Principles of Green Chemistry" more than 20 years ago, chemists have become increasingly mindful of the need to conserve natural resources and protect the environment through the judicious choice of synthetic routes and materials. The direct activation and functionalization of C-H bonds, bypassing intermediate functional

Tandem C–O and C–H Activation at Palladium Enables Catalytic Direct C–H Alkenylation with Enol Pivalates [PDF]

open access: yes, 2021
The use of oxygen-based electrophiles in cross-coupling remains challenging for substrates with strong C–O bonds, with few examples that can combine C–O activation with an-other strong-bond activation in tandem.

C–H Functionalization/activation in organic synthesis [PDF]

open access: yesBeilstein Journal of Organic Chemistry, 2016
The last decade has seen an explosion in research reports in the area of C–H functionalization/activation in organic synthesis. This is not surprising. What is surprising is that it took many in the synthetic organic community this long to fully embrace this exciting and enabling technology.

δ-C(sp3)H Activation of Free Alcohols Enabled by Rationally Designed H-Bond-Acceptor Ligands [PDF]

open access: yes, 2023
The ability to employ a wide range of native substrates is essential for the broad application of transition-metal-catalyzed C–H activation. Recent advances have made native carboxylic acids, ketones, and amines amenable to C(sp3)–H activation, but ...

C—H Activation of Unbiased C(sp3)—H Bonds [PDF]

open access: yes, 2022
The selective functionalization of non-activated C(sp3)—H bonds is a major challenge in chemistry. Here, we have developed an [Au]-catalyzed C(sp3)-H activation of common 1 bromoalkynes into a library of diverse 3D-scaffolds.
