2024-06-05: Congratulations to Xun Zhang and Jianxu Chen! ACS Catal. BINOL can serve as not only chiral ligands, but also as photoredox and photoacid catalysts!   

The orthogonality of different types of living polymerizations allows the synthesis of polymers with diverse compositions and functions. However, two or more catalysts are normally required to promote the integrated polymerizations separately and few could deliver a photocontrol on both polymerizations. Herein, we demonstrate BINOL (1,1’-bi-2-naphthol) with appropriate modification can be evolved into a type of dual-function photocatalysts, and exhibit both photoredox and photoacid catalytic activity at the same time. This dual photo-functions could enable BINOLs to catalyze the metal-free atom transfer radical polymerization and ring-opening polymerization with a simultaneous light regulation. The utility of this orthogonal method is further demonstrated in the one-pot synthesis of PMMA-b-PVL block copolymers with good control on both molecular weight and low dispersity.

2024-06-04: Congratulations to Peng Wang and Lu Lin, the work on radical fluorosulfonamidation has been published on Angew. Chem. We also introduced a redox-active radical agent, FSAP. Further application of FSAP in molecule synthesis and reaction development can be expected.

Recently, the introduction of fluorosulfonyl (-SO2F) groups have attracted considerable research interests, as this moiety could often afford enhanced activities and new functions in the context of chemical biology and drug discovery. Herein, we report the design and synthesis of 1-fluorosulfamoyl-pyridinium (FSAP) salts, which could serve as an effective photoredox-active precursor to fluorosulfamoyl radicals and enable the direct radical C−H fluorosulfonamidation of a variety of (hetero)arenes. This method features mild conditions, visible light, broad substrate scope, good group tolerance, etc., and a metal-free protocol is also viable by using organic photocatalysts. Further, FSAP can also be applied to the radical functionalization of alkenes via 1,2-difunctionalization, radical distal migration, tandem radical-polar crossover reactions, etc. In addition, a formal C-H methylamination of (hetero)arenes by combining this radical C−H fluorosulfonamidation with subsequent hydrolysis as well as product derivatization are also demonstrated.

2024-2-05: Congratulations to Zan Yang! Now, photocontrolled cationic polymerzation could proceed with high stereoselectivity, to afford isotactic polymer products.


Employing an ion pair photoredox catalyst consisting of a photoredox-active cationic part and a sterically confined chiral anion to deliver the stereochemical control, a highly stereoselective cationic polymerization with concurrent stereo-regulation and light control has been successfully achieved.
