In this Comment, we suggest salt metathesis (or ion exchange) as an ultimate click reaction, extending click chemistry principles beyond covalent bonds to ionic interactions. These universal and robust reactions, which nature utilizes in marine organisms' biomineralization processes, proceed spontaneously under mild conditions with minimal waste, embodying the core principles of click philosophy. This perspective expands the traditional scope of click chemistry and opens new opportunities in synthetic accessibility across organic, inorganic, and materials science spaces.

Nitroso compounds, R-N═O, containing N═O double bonds are ubiquitous and widely utilized in organic synthesis. In contrast, heavier congeners of nitroso compounds, namely pnictinidene chalcogenides R-Pn = E (Pn = P, As, Sb, Bi; E = O, S, Se, Te), are highly reactive and scarce. They have been stabilized in the coordination sphere of Lewis acid/base or by pronounced contribution from resonance structures, whereas free species with unperturbed pnictogen-chalcogen double bonds remains elusive.

The metathetical modification of biomolecules in aqueous environments holds great promise for advances at the interface of chemistry, biology, and medicine. However, rapid degradation of the metathesis catalysts necessitates their use in large stoichiometric excess, resulting in undesired side-reactions promoted by the ruthenium products. Although water is now known to play a central role in catalyst decomposition, the elusive nature of the intermediates has hampered insight into the pathways involved.

Herein, we report an unprecedented NHC ligand substitution around a ruthenium center, exploiting an orthometalated complex. Captivatingly, the employed metal complex here undergoes a unique σ-bond metathesis in the presence of an alkene and azolium salt, leading to facile exchange of ancillary NHC ligands at the Ru-center, which is not known to the best of our knowledge.

This work explores the use of plumbylene-phosphinidenes to address the challenge of isolating P=Pb bonds. Herein, we report the synthesis of three N-heterocyclic carbene phosphinidene (NHCP) substituted chlorotetrylene dimers [(IDipp)PECl] (E=Ge, Sn, Pb; IDipp=C([N-(2,6-Pr-CH)CH])). Substituent attachment via salt metathesis (E=Sn, Pb) enables the isolation of NHCP-silyl-substituted stannylene (IDipp)PSn(SiTmsSiTol) as well as NHCP-silyl- and NHCP-aryl-substituted plumbylenes (IDipp)PPb(SiTmsSiTol) and (IDipp)PPb(Ter) (Ter=2,6-MesCH, Tms=Trimethylsilyl).
