Abstract

The mechanisms of carbonylation of alkenes, alkynes, and alcohols, including the mechanism of oxidative carbonylation of alkynes in the regime of self-oscillations catalyzed by Pd(II), Pd(I), or Pd(0) complexes, are analyzed. It is shown that the main reasons for the appearance of self-oscillations in the oxidation reactions are nonlinear and autocatalytic steps of generation and termination of active centers. The results of studying the functions of para-benzoquinone as an oxidant, ligand, and catalyst in the oxidative reactions are generalized. It is found that Pd(0) complexes with para-benzoquinone can catalyze oxidation reactions.
