Structure and Reactivity of Nonporphyrinic Terminal Manganese(IV)-Hydroxide Complexes in the Oxidative Electrophilic Reaction.

High-valent transition metal-hydroxide complexes have been proposed as essential intermediates in biological and synthetic catalytic reactions. In this work, we report the single-crystal X-ray structure and spectroscopic characteristics of a mononuclear nonporphyrinic Mn-(OH) complex, [Mn(Me-TPADP)(OH)(OCHCH)] (), using various physicochemical methods. Likewise, [Mn(Me-TPADP)(OH)(OCHCF)] (), which is thermally stable at room temperature, was also synthesized and characterized spectroscopically.
