The perceived toxicity of organometallic reagents has limited their use in living systems. Now it has been shown that balancing flexible chelation with biocompatible ligands without precluding chemical reactivity enables organonickel-mediated S-arylation inside cells. This reaction enables deep chemical surveys of reactive proteins and covalent tracking of intracellular viral and bacterial pathogens.
