A highlyselectivePd/Cu‐cocatalyzed aerobicoxidativecarbonylativehomocoupling of arylboronicacids has been developed. This method employs a simple catalytic system, readily available boronic acids as the substrates, molecular oxygen as the oxidant, and 1 atm of CO/O2, which makes this method practical for further applications.

reductive cross-coupling reaction between two electrophiles, amides and aryl iodides, has been developed. This work is the first example using amide as an electrophile to couple with another electrophile, instead of using highly basic and pyrophoric nucleophiles. Furthermore, the Ni catalyst chemoselectively inserting the C–N bond of amide triggered the reductive cross-coupling reaction, which solves the
