UCLA chemists have made dramatic improvements in organic chemistry. They use oxygen, copper ‘scissors’ to make cheaper drug treatments possible. Zhiqi He et al, Aminodealkenylation: Ozonolysis and copper catalysis convert C(sp 3 )–C(sp 2 ) bonds to C(sp 3 )–N bonds, Science (2023). Editor’s summary Reactions that form carbon–nitrogen bonds most often target carbon centers …
