Journal ArticleDOI
Two-State Reactivity as a New Concept in Organometallic Chemistry§
TL;DR: The present analysis is based on studies of transition metals under idealized conditions, and several recent reports imply that TSR is by no means confined to the gas phase.
Journal ArticleDOI
The singlet and triplet states of phenyl cation. A hybrid approach for locating minimum energy crossing points between non-interacting potential energy surfaces
TL;DR: The lifetime of the phenyl cation is expected to be very short as discussed by the authors, and the minimum energy crossing point between these two surfaces, located at various levels including a hybrid method first described here, lies just above the minimum of the triplet, 0.12 kcal/mol.
Journal ArticleDOI
Gas-phase catalysis by atomic and cluster metal ions: the ultimate single-site catalysts.
Diethard K. Bohme,Helmut Schwarz +1 more
TL;DR: This Review describes how transfer of oxygen atoms, bond activation, and coupling of fragments can be mediated by atomic or cluster metal ions, and improves the understanding of the intrinsic operation of a practical catalyst at a strictly molecular level.
Journal ArticleDOI
Chemistry with Methane: Concepts Rather than Recipes
TL;DR: Four seemingly simple transformations related to the chemistry of methane are addressed from mechanistic and conceptual points of view: metal-mediated dehydrogenation to form metal carbene complexes, the hydrogen-atom abstraction step in the oxidative dimerization of methane, the mechanisms of the CH(4)→CH(3)OH conversion, and the initial bond scission.
