“…Oxidative alkenylation of unactivated CÀ H bond represents an important reaction type in organic synthesis. [68][69][70][71][72][73][74] A wide range of rhodium(III)-catalyzed CÀ H alkenylations have been realized in the presence of stoichiometric chemical oxidants, typically silver(I) or copper(II) salts. [38,75] In sharp contrast, the Ackermann group reported the first electrochemical rhodium-catalyzed oxidative CÀ H alkenylation without stoichiometric chemical oxidants (Scheme 3).…”

Rhodium-catalyzed CÀ H activation has emerged as a powerful tool for forging CÀ C and C-heteroatom bonds. Nevertheless, the requirement of stoichiometric chemical oxidants for oxidative transformations significantly hampered the overall sustainability of the CÀ H activation transformations. The emergence of merging transition metal catalysis and electrochemistry, called metalla-electrocatalysis provides an excellent opportunity to construct organic molecules efficiently and sustainably. This review highlights the recent developments of rhodium-catalyzed electrochemical CÀ H activation transformations, challenges and opportunities for future developments.

“…Over the past few decades, outstanding progress has been realized in the direct alkenylation transformation of C(sp 2 )-H bonds [95][96][97][98][99][100][101]. However, the related C(sp 3 )-H alkenylation is much less developed due to lower reactivity, poor regioselectivities and the need of noble metal catalysts [50,[102][103][104][105][106].…”

Catalytic C‒H functionalization has become a powerful strategy in organic synthesis due to the improved atom-, step- and resource economy in comparison with cross-coupling or classical organic functional group transformations. Despite the significant advances in the metal-catalyzed C‒H activations, recent developments in the field of metallaphotoredox catalysis enabled C‒H functionalizations with unique reaction pathways under mild reaction conditions. Given the relative earth-abundance and cost-effective nature, nickel catalysts for photoredox C‒H functionalization have received significant attention. In this review, we highlight the developments in the field of photoredox nickel-catalyzed C‒H functionalization reactions with a range of applications until summer 2021.
