A convenient, efficient and practical visible-light-induced decarboxylative iodination of aromatic carboxylic acids has been developed, and the corresponding aryl iodides were obtained in good yields. The method shows some advantages including the use of readily available aromatic carboxylic acids as the starting materials, simple and mild conditions, high efficiency, wide substrate scope and tolerance of various functional groups.

AbstractThe flourishing Ni/photoredox-catalyzed asymmetric couplings typically rely on redox-neutral reactions. In this work, we report a reductive cross-coupling of aryl iodides and α-chloroboranes under a dual catalytic regime to further enrich the metallaphotoredox chemistry. This approach proceeds under mild conditions (visible light, ambient temperature, no strong base) to access the versatile benzylic boronic esters with good functional group tolerance and excellent enantioselectivities.

Wide Range

A new visible-light-induced Ir(III)-catalyzed difluoroalkylation–bicyclization of 1,7-enynes with ethyl 2-bromo-2,2-difluoroacetate (BrCF2CO2Et) is described, furnishing a wide range of difluoromethyl-containing benzo[a]fluoren-5-ones in good to excellent yields. The reaction is operationally simple, proceeds with high efficiency under mild conditions, and shows excellent functional group compatibility.

A Ni-catalyzed enantioselective reductive diarylation of alkenes through a tandem Heck cyclization/cross coupling of two structurally distinguished aryl bromides is accomplished for the first time. This reaction takes place under very mild conditions with high efficiency and tolerates a variety of functional groups. Thus, it provides a rapid access to various medicinally relevant bis-heterocycles containing all-carbon quaternary centers with very high enantioselectivity.
