The Fe-MAN Challenge: Ferrates–Microkinetic Assessment of Numerical Quantum Chemistry Open
Organometallic species, such as organoferrate ions, are prototypical nucleophiles prone to reacting with a wide range of electrophiles, including proton donors. In solution, the operation of dynamic equilibria and the simultaneous presence…

Gas‐Phase Alkali‐Metal Cation Affinities of Stabilized Enolates Open
The chemistry of alkali‐metal enolates is dominated by ion pairing. To improve our understanding of the intrinsic interactions between the alkali‐metal cations and the enolate anions, we have applied Cooks’ kinetic method to determine rela…

C versus O Protonation in Zincate Anions: A Simple Gas‐Phase Model for the Surprising Kinetic Stability of Organometallics Open
For better understanding the intrinsic reactivity of organozinc reagents, we have examined the protolysis of the isolated zincate ions Et 3 Zn − , Et 2 Zn(OH) − , and Et 2 Zn(OH) 2 Li − by 2,2,2‐trifluoroethanol in the gas phase. The proto…
Barriers of Protonation Reactions of Organometallics Open
Protonation reactions are entirely understood for simple organic and inorganic molecules and there are elaborated concepts to describe such acid-base reactions in both the solution and gas phase. For organometallic species, however, there …

In‐Situ Analysis of Anionic Coordination Polymerizations by Electrospray‐Ionization Mass Spectrometry Open
Anionic coordination polymerizations proceed via highly reactive intermediates, whose in situ analysis has remained difficult. Here, we show that electrospray‐ionization mass spectrometry is a promising method to obtain detailed informatio…
