The same is not the same(II): Sunaina shows that a-nitroradicals formed via Cu(II)-photooxidation of nitroalkanes undergo formal [3+2]-cycloadditions with alkynes/alkenes, greatly broadening the concerted pathway (Machetti reaction). https://t.co/rX7ZNDrum9

New method for N-arylation of amines in DNA-encoded libraries! Using ruthenium-mediated pi-arene activation, aryl halides are activated, then undergo SNAr followed by photolysis to give the N-arylated DNA-conjugate.
