μ-Carbido diruthenium(IV) bis-phthalocyanine [Ru^tBuPc]₂C as well as its axially coordinated derivatives (N-bases are imidazole Im, 1-methylimidazole 1-MeIm, benzimidazole BzIm) interact with ^tBuOOH in benzene resulting the generation of powerful high-valent species (π-cation radical or Ru^V-oxo species) which are competent in β-carotene oxidation at room temperature in several minutes. The transient reactive compounds were characterized based on UV–visible, IR spectroscopy and electrochemistry data. Electron-rich axial N-base ligands significantly stabilize highly reactive Ru^V-oxo bis-phthalocyanine species those mediate the simultaneous oxidation both β-carotene and ^tBuOOH in the studied systems. Catalytic behavior of all the observed transient oxidants is supported by recycling of the reaction under carotene adding. Insight gained into the diruthenium bisphthalocyanine systems is useful for the design of new highly efficient binuclear ruthenium-catalysts for oxidation reactions under mild conditions, and for extension of knowledge to Ru^V-species to develop highly active and selective catalysts.
