Cooperative activating effects of metal ion and Bronsted acid on a metal oxo species.

ABSTRACT: Metal oxo (M[double bond, length as m-dash]O) complexes are common oxidants in chemical and biological systems. The use of Lewis acids to activate metal oxo species has attracted great interest in recent years, especially after the discovery of the CaMn₄O₅ cluster in the oxygen-evolving centre of photosystem II. Strong Lewis acids such as Sc³⁺ and BF₃, as well as strong Brønsted acids such as H₂SO₄ and CF₃SO₃H, are commonly used to activate metal oxo species. In this work, we demonstrate that relatively weak Lewis acids such as Ca²⁺ and other group 2 metal ions, as well as weak Brønsted acids such as CH₃CO₂H, can readily activate the stable RuO₄ ^- c
