Abstract

Deprotonation and two-electron oxidation of [Ru^II₂(OH)₂(Q)₂(btpyan)]²⁺ (Q = 3,6-di(tert-butyl)-1,2-quinone, btpyan = 1,8-bis(2,2′:6′,2″-terpyridyl)anthracene) was converted to bis(ruthenium-oxo) complex [Ru¹¹₂(O)₂(Q)₂(btpyan)]²⁺ , which oxidized 1,3-cychrohexadiene and 1,2-dihydronaphtalene to corresponding aromatic compounds in the presence of AgClO₄ and t-BuOK. On the other hand, mononuclear complex [Ru^II(OH₂)(Q)(Ph-terpy)]²⁺ (Ph-terpy = 4′-phenyl-2,2′: 6′,2″-terpyridine, [2]²⁺) was converted to [Ru^II(OH)(Q)(Phterpy)]²⁺ under the similar conditions, but displayed the low activity for the oxidation compared with the dinuclear complex [1]²⁺.
