Abstract

This chapter surveys mechanistic computational studies on the activation of CX single bonds mediated by transition-metal centers. X can be based on any element of groups 13-17 and 'mechanistic' indicates that the transition state for CX bond activation has been located. Bond activation itself refers to the cleavage of a CX bond such that both partners may (potentially) act as neutral one-electron donors to the metal center. This definition covers oxidative addition, typically via a concerted and also by SN2 or radical processes; also included are σ-bond metathesis, as well as CX cleavage promoted by Lewis acidic and Lewis basic species. The reactivity of neutral transition atoms and cations (often modeling gas-phase experimental reactivity) and of molecular complexes (of relevance to solution-phase reactivity and homogeneous catalysis) is discussed.
