A series of stable salts of the oxidized donors TTF, o-Me2TTF,TMTTF, and TTF(SCH2CH2CN)4

Reactions of the organic donors tetrathiafulvalene (TTF), o-dimethyltetrathiafulvalene (o-Me₂TTF), tetramethyltetrathiafulvalene (TMTTF), and tetrathiafulvalene tetrathiolate TTF(SCH₂CH₂CN)₄] with oxidizing agents of suitable potential resulted in the formation of stable salts in which the donors are present in their monocationic radical forms. The salts presented herein represent a series of reagents containing oxidized chalcofulvalene donors that can be used as starting materials for metathesis reactions with other cations. All of the salts were characterized by X-ray crystallography and UV–vis–NIR spectroscopy.
