Nickel-Catalyzed Regiodivergent Reductive Hydroarylation of Styrenes

Abstract: We report a ligand-controlled nickel-catalyzed reductive hydroarylation of styrenes with predictable and controllable regioselectivity. With a diamine ligand, the reaction produces selective linear hydroarylation products. Alternatively, with a chiral PyrOx ligand. branch-selective enantio-enriched 1,1-diarylalkane products are obtained. Preliminary mechanistic results are consistent with a reductive Heck process.

“…Hydroarylation reactions involving catalytic organoligand/Ni systems and pre-activated arene are more represented compared to the direct counterpart (Section 2.4). Between 2019 and 2021 Zhu's group published several works in high-impact journals where the catalytic systems involved Nickel and preactivated arenes in hydroarylation reactions [67][68][69][70][71]. At first, a racemic version of the hydroarylation of boron-containing alkenes (80) was reported.…”

“…Following up their ongoing interest in the field, Jarvo describes a new protocol for streamlining the preparation of fluorinated cyclopropanes, 21 whereas Zhu and He describe the ability of ancillary ligands to dictate the site-selectivity in a Ni-catalyzed reductive hydroarylation of styrene motifs. 22 Chu, 23 Fensterbank, 24 Martin 25 and Amgoune 26 merge photoredox catalysis and Ni catalysts to enable dual functionalization of vinyl boranes, monoalkylation of dichlorostyrenes, photodehalogenation of organic halides, and sp 3 C-H acylation events with N-acyl imides. Last but not least, Diao offers a versatile tool for synthetic organic and organometallic chemists by tabulating experimentally measured redox potentials of Ni complexes supported by commonly employed ligands.…”
