摘要：

We will examine the reaction mechanisms and energetics of C-H bond activation catalyzed by several high-valent Ru, Mn, and Fe oxo complexes. These complexes include: (i) seven-coordinate Ruthenium iodosylbenzene; (ii) Ruthenium tetraoxide and perruthenate; (iii) permanganate; (iv) protonated ferrate Our theoretical findings indicate that the oxidation of hydrocarbons can be accelerated in the presence of Lewis or Brønsted acids. In our density functional theory and polarization continuum model calculations, we will consider not only the electronic ground state but also the excited states of these species, as well as the solvent effects on the reaction mechanisms.
