Nickel-catalyzed decarbonylative C-H coupling reactions: A strategy for preparing bis(heteroaryl) backbones

The direct arylation of heteroarenes was accomplished by employing aromatic esters as effective coupling partners under nickel catalysis (see scheme; Z=O, S). The key process implies an unconventional and unprecedent Ni-catalyzed decarbonylative coupling utilizing cost-efficient.
