Abstract: Carbonylation of arylboronic acid derivatives employing Cr(CO)6 as the carbonyl source and NiCl2(dmg)/4,4′‐bipy as the catalyst under air without applying external oxidant has been reported for the amide and ester synthesis (dmg=dimethylgloxime; bipy=bipyridine). Moreover, CHCl3 was also used as another carbonyl source for the amide synthesis with CuI/1,10‐phenanthroline catalytic system.
