  • CO2 can be used as an activator for the direct transformation of abundant and unprotected primary aliphatic amines into valuable γ-lactams under photoredox and hydrogen-atom-transfer catalysis. Electrostatic interactions between the in situ generated alkylammonium carbamate and the positively charged quinuclidinium radical lead to regioselective hydrogen atom abstraction.

  • Existing methods for C–H activation depend on pre-installed directing groups, the removal of which poses a practical limitation on the use of these reactions in synthesis. Now, a remote-selective C−H alkylation reaction of arenes using an in situ generated spiropalladacycle has been shown to furnish benzofurans and indoles without the need for a directing group.
