A hypervalent iodine(iii) reagent catalyzed carbonylarylation of acrylamides with α-oxocarboxylic acids driven by visible-light without a photoredox catalyst has been developed. The reactions generate the corresponding products in good yields at room temperature. Experiments indicate that a blue LED (450-455 nm) is the most effective energy for the cleavage of the oxygen-iodine bond to initiate the reaction. Mechanistic studies further demonstrate that the reaction undergoes a cascade decarboxylative radical addition/cyclization process along with releasing CO2 and H2.

An efficient method for oxindole synthesis is established by iron-catalyzed carbonylation-arylation of N-arylacrylamides with aldehydes. 3-Functionalized oxindoles are synthesized smoothly using FeCl3 as catalyst and TBHP as oxidant. The obtain

A mild and efficient silver-catalyzed acyl- arylation of activated alkenes with easily available α-oxocarboxylic acids has been developed. The reactions provide a rapid access to a variety of functionalized oxindoles via a tandem decarboxylative radical cyclization strategy. This transformation proceeds well under mild reaction conditions and exhibits excellent functional group tolerance, affording the desired oxindoles in good to excellent yields.
