Selective C(sp3)–H arylation/alkylation of alkanes enabled by paired electrocatalysis [PDF]

open access: yesNature Communications, 2023
We report a combination of electrocatalysis and photoredox catalysis to perform selective C(sp3)–H arylation/alkylation of alkanes, in which a binary catalytic system based on earth-abundant iron and nickel is applied.

Kinetic Resolution of Sulfur-Stereogenic Sulfoximines by Pd(II)-MPAA Catalyzed C-H Arylation and Olefination [PDF]

open access: yes, 2021
A direct Pd(II)-catalyzed kinetic resolution of heteroaryl-enabled sulfoximines through an ortho-C-H alkenylation/arylation of arenes has been developed for the first time.

Pd(II)-Catalyzed Synthesis of Benzocyclobutenes by β-Methylene-Selective C(sp3)‒H Arylation with a Transient Directing Group [PDF]

open access: yes, 2021
Methylene-selective C‒H functionalization is a significant hurdle that remains to be addressed in the field of Pd(II) cataly-sis. In this paper we report a Pd(II) catalyzed synthesis of benzocyclobutenes by methylene-selective C(sp3)‒H arylation of ...

Twofold C-H Activation-Based Enantio- and Diastereoselective C-H Arylation Using Diarylacetylenes as Rare Arylating Reagents [PDF]

open access: yes, 2021
C-H bond activation has been established as an attractive strategy to access axially chiral biaryls, and the most straightforward method is direct C-H arylation of arenes.

Synthesis of Novel 3,6-Dithienyl Diketopyrrolopyrrole Dyes by Direct C-H Arylation

open access: yesMolecules, 2020
Direct C-H arylation coupling is potentially a more economical and sustainable process than conventional cross-coupling. However, this method has found limited application in the synthesis of organic dyes for dye-sensitized solar cells. Although direct C-

Copper-catalyzed asymmetric C(sp2)–H arylation for the synthesis of P- and axially chiral phosphorus compounds

open access: yesNature Communications, 2023
Transition metal-catalyzed C–H bond functionalization is an important method in organic synthesis, but the development of methods that are lower cost and have a less environmental impact is desirable. Here, a Cu-catalyzed asymmetric C(sp2)–H arylation is
