Herein, we report the development
of a tailored cobalt catalyst
system of Cp*Co(III)(LX) toward intramolecular C–H nitrene
insertion of azidoformates to afford cyclic carbamates. The cobalt
complexes were easy to prepare and bench-stable, thus offering a convenient
reaction protocol. The catalytic reactivity was significantly improved
by the electronic tuning of the bidentate LX ligands, and the observed
regioselectivity was rationalized by the conformational analysis and
DFT calculations of the transition states. The superior performance
of the newly developed cobalt catalyst system could be broadly applied
to both C(sp2)–H and C(sp3)–H
carbamation reactions under mild conditions.
