Abstract

Oxidative degradation and transformation of catalysts are commonly observed in water oxidation by molecular catalysts, especially when a highly oxidizing reagent such as (NH₄)₂[Ce(NO₃)₆] [Ce(iv)] is used. We report herein the synthesis of a ruthenium(iii) complex bearing an oxidative resistant bipyridine-bis(alkoxide) ligand, [Ru(bdalk)(pic)₂]⁺(1, H₂bdalk = 2,2′-([2,2′-bipyridine]-6,6′-diyl)bis(propan-2-ol), pic = 4-picoline) as a water oxidation catalyst (WOC). A ruthenium(ii) nitrosyl complex [Ru(Hbdalk)(NO)(pic)₂]²⁺(3) was also formed during the water oxidation process by1/Ce(iv), and was isolated and structurally characterized. Complex3was found to be an active WOC, with the nitrosyl group remaining intact during water oxidation.
