The oxidative electrochemistry of porphyrin- and non-porphyrin-based ruthenium nitrosyl phenoxides is compared. The consequences of oxidation of Ru(por)(NO)(OAr) and and Ru(tBu4sal)(NO)(OAr’) are explored (por = tetratolylporphyrin, tetraanisolylporphyrin; Ar = OC6H5, 2-(NHC(O)CF3)C6H4, 2,6-(NHC(O)CF3)2C6H3) (tBu4sal = trans-1,2-cyclohexane-bis-(3,5-di-tertbutyl)salicylidene aminate or 1,2-benzene bis-(3,5-di-tertbutyl)salicylidene aminate, Ar’ = C6H5, p-C6H4CF3). Results from cyclic voltammetry, in-situ fiber-optic IR spectroelectrochemistry, EPR spectroelectrochemistry and DigiElch simulation will be presented.

Electrochemical investigations of phenoxide derivatives of ruthenium nitrosyl complexes

Where thousands of chemistry professionals meet to share ideas and advance scientific and technical knowledge. Spring 2023 abstracts, posters, and presentations will launch at the end of March.
