Abstract
[Ru-III(amp)(bipy)(H2O)](+) complex (1) has been synthesized and characteri zed by physico-chemical methods. The complex 1 is found to be an effective catalyst in the oxidation of benzene to phenol by using tert-butylhydropero xide (t-BuOOH). A high valent Ru(V)-oxo species as catalytic intermediate f ormed in the reaction of 1 with t-BuOOH is proposed to be the source of oxy gen atom in the oxidized product. A mechanism involving stacking of benzene followed by the O atom insertion seems to be operative in the formation of phenol from benzene. (C) 2001 Elsevier Science B.V. All rights reserved.
