Abstract ：
We report here an electrophotoredox cerium-catalyzed ligand-to-metal-charge-transfer (LMCT) strategy to incorporate a broad range of primary, secondary and tertiary carboxylic acids into radical cyclization cascades under external oxidant-free conditions. This protocol provides a solution to address the challenges associated with alkylated benzimidazo-fused isoquinolinones synthesis. The high functional group compatibility was demonstrated by the tolerance of ester, carbonyl, amide, sulfonyl and hydroxyl groups. We report an electrophotoredox cerium-catalyzed LMCT strategy to incorporate carboxylic acids into radical cyclization cascades. This protocol provides a solution to address the challenges in alkylated benzimidazo-fused isoquinolinone synthesis.

Abstract ：
Sodium sulfinates have been widely utilized as sulfonyl radical precursors for preparing a diverse array of value-added sulfur-containing compounds (sulfones, sulfonamides, sulfonates, thiosulfonates, etc.) through S-C, S-N, S-O and S-S bonds formation reactions. Organic electrosynthesis has become an attractive alternative to conventional methods for redox reactions because it utilizes electric current instead of chemical redox agents. As such, the electrochemical generation of sulfonyl radicals from sodium sulfinates and their applications in organic electrosynthesis have attracted much attention. In this review, the recent advances in the electrochemical sulfonylation of organic compounds involving sodium sulfinates as sulfonyl radical precursors since 2015 were reviewed, along with related reaction mechanisms.

Abstract ：
Reported herein is the design of a new catalytic paradigm by synergistically combining sequential paired electrosynthesis with halogen-bonding (XB) activation for the cyclization of organochlorides with olefins. This dual activation strategy enables rapid access to densely functionalized 2-alkylidene-tetrahydrofurans with exclusive Z-selectivities, which are challenging to be synthesized by other methods. 4,4'-Di-tert-butyl-2,2'-bipyridine (dtbbpy) showed an unprecedented reactivity as a XB acceptor to activate C-Cl bond by shifting its reduction potential positively by 220 mV. Distinctly different from previous electroreductions of C-Cl bonds relying upon high electrode potentials or matched redox properties between mediators and organochlorides, the XB activator employed herein has no limit on the abovementioned redox property matching but can lower the applied electrode potentials. The decreased operating potential allows broad functional group tolerance, which was highlighted by the late-stage functionalization of 11 examples of drugs and natural products-derived alkenes.

Abstract ：
A new electrochemical strategy for the atom transfer radical addition (ATRA) of polychloroalkanes across olefins has been realized by the synergism of paired electrolysis and halogen bonding activation. Notably, readily accessible 4,4-di-tert-butyl bipyridine (dtbpy), acting as a halogen bonding acceptor, shifted the reduction potential of C-Cl bonds positively by 110 mV. The decreased operating potential leads to a wide substrate scope and excellent functional group compatibility. A diverse array of terminal and internal alkenes such as (hetero)aryl olefins, unactive aliphatic olefins, and natural products and drugs-derived olefins were well compatible.

Abstract ：
The Minisci alkylation of N-heteroarenes with unactivated alkanes under external oxidant-free conditions provides an economically attractive route to access alkylated N-heteroarenes but remains underdeveloped. Herein, a new electrophotocatalytic strategy to access alkyl radicals from strong C(sp(3))-H bonds was reported for the following Minisci alkylation reactions in the absence of chemical oxidants. This strategy realized the first example of cerium-catalyzed Minisci alkylation reaction directly from abundant unactivated alkanes with excellent atom economy. It is anticipated that the general design principle would enrich catalytic strategies to explore the functionalizations of strong C(sp(3))-H bonds under external oxidant-free conditions with H-2 evolution.

Abstract ：
The organoselenium-catalyzed amination of alkenes is a promising way to construct functionalized amines. However, the use of chemical oxidants and the unavoidable formation of allylic amine or enamine are the two main limitations of these methodologies. Against this background, we herein report an electro-selenocatalytic regime for the hydroazolylation of alkenes with azoles under external oxidant-free conditions with low catalyst loadings. Moreover, this protocol enables the generation of amines without vinyl substituents.

An efficient copper-catalyzed vicinal C(sp(2)).H selenylation of benzoic acid dervatives is reported using diselenyl ether as selenyl resource, 8-aminoquinoline as the directing group. The protocol need only air as the terminal oxidant, avoiding the utilization of other external chemical oxidants, featuring good substrates generality and compatiblity of functional groups.
