Catalytically Relevant Intermediates in the Ni-Catalyzed C(sp2)-H and C(sp3)-H Functionalization of Aminoquinoline Substrates
This Article describes the synthesis and characterization of cyclometalated aminoquinoline NiII sigma-aryl and sigma-alkyl complexes that have been proposed as key intermediates in Ni-catalyzed C-H functionalization reactions. These NiII complexes serve as competent catalysts for the C-H functionalization of aminoquinoline derivatives with I2. They also react stoichiometrically with I2 to form either aryl iodides or beta-lactams within minutes at room temperature. Furthermore, they react with AgI salts at -30 C to afford isolable five-coordinate NiIII species. The NiIII sigma-aryl complexes proved inert toward C(sp2)-I bond-forming reductive elimination under all conditions examined (up to 140 C in DMF). In contrast, a NiIII sigma-alkyl analogue underwent C(sp3)-N bond-forming reductive elimination at 140 C in DMF to afford a beta-lactam product. However, despite the ability of this latter NiIII species to participate in stoichiometric product formation, the complex was not a competent catalyst for beta-lactam formation. Overall, these results suggest against the intermediacy of NiIII species in these C-H functionalization reactions.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 17347-61-4
