Ni-Catalyzed Divergent Cyclization/Carboxylation of Unactivated Primary and Secondary Alkyl Halides with CO₂

A user-friendly Ni-catalyzed reductive cyclization/carboxylation of unactivated alkyl halides with CO2 is described. The protocol operates under mild conditions with an excellent chemoselectivity profile and a divergent syn/anti selectivity pattern that can be easily modulated by the substrate utilized.
