Chemistry of Transition Metal Heterocyclic Complexes, II. Synthesis and Electrochemistry of Carbonyl Chromium Complexes in the Bithiophen SeriesThe (substituted) (bithiophene)tricarbonylchromium complexes 4a - g are formed in yields up to 95% upon treatment of tricarbonyltris(γ-picoline)chromium with 2,2′-bithiophene (1a) and its derivatives 1b - e and 1g, respectively, in the presence of the Lewis acid BF3. The oxidation of the new compounds, as investigated by means of cyclovoltammetry, is irreversible and effects decomposition of the complexes.
Notes:
Durch Umsetzung von Tricarbonyltris(γ-picolin)chrom (3) mit 2,2′-Bithiophen (1a) und seinen Derivaten 1b - e und 1g bilden sich in Gegenwart der Lewis-Säure BF3 die (substituierten) Bithiophen-Chromtricarbonyl-Komplexe 4a - g in Ausbeuten bis 95%. Die cyclovoltametrisch untersuchte Oxidation der neuen Verbindungen verläuft irreversibel unter Zerfall der Komplexe.
