Many high-profile examples of photoredox catalysis are proposed to proceed via excitation of an open-shell intermediate form of the catalyst. However, there is much debate over whether such mechanism...

For advancing the chemistry of geometrically constrained heavy pnictogen pincer compounds to access exotic radical states and unique transition metal mimetic reaction pathways.

In this communication, we revisit one of E. O. Fischer’s seminal discoveries to solve a textbook question: is the iron(0) complex [Fe(C6Me6)2] an 18-valence-electron complex with a ‘ring-slip’ (η6,η4)...

Using a reductive group elimination strategy, heavier alkyne (LEEL; E = Sn, Pb) complexes of Ni0 are accessed. In contrast to classical alkyne coordination, these systems are best described as σ-comp...

Phosphonioacetylides are rod-shaped, neutral carbon donors with ambiphilic character at the terminal carbon. Despite their analogy to CO and isocyanides, they remain underexplored due to their high reactivity, and only one isolable free phosphonioacetylide has been reported. Here, we describe two new isolable, room-temperature-persistent examples stabilized either by two N-heterocyclic imines (NHIs) bearing bulky, flexible tert-octyl groups or by a single dipp-substituted NHI combined with alkyl substituents. Comprehensive characterization (SCXRD, NMR, IR, MS, DFT) confirms their strong donor properties and the accessibility of the reactive C2 unit. DFT analysis quantify how the substituents at phosphorus modulate the frontier molecular orbital energies, spanning a wide range of σ and π-donor strengths and π-acceptor abilities, with trends that mirror those of the corresponding phosphines. Both phosphonioacetylides readily form AuI complexes, whereas the less electron-rich compound shows the tendency to eliminate its C2 moiety thermally or upon hydrolysis. These results establish design principles for stabilizing and tuning phosphonioacetylides and open avenues for their use in coordination chemistry and catalysis.
