Metal‐Free Scission of the NO+ Triple Bond
Angewandte Chemie International Edition, Volume 65, Issue 13, 23 March 2026.Breaking bonds: The reaction between NO[Al(ORF)4] (RF = C(CF3)3) and the diphosphane PNPtBu (2,6‐bis(di‐tert‐butylphosphino‐methyl)pyridine) leads to the direct and complete cleavage of the NO+ triple bond, one of the strongest chemical bonds known. The mechanism of this reaction was studied using quantum chemical calculations and NMR spectroscopic ...

Angewandte Chemie, Volume 138, Issue 10, 2 March 2026.Coordination of a Lewis base switches an electron‐accepting tricoordinate boron center into an electron‐donating tetracoordinate one. An alkenyl‐strapped diphenylthienylboryl π‐system undergoes phosphine‐induced reversible π‐umpolung, where transformation from an acceptor–acceptor–acceptor framework to a donor–acceptor–donor system gives rise to ...
