Cyclic Voltammetry (EG&G Princeton Applied Research Model 263A potentiostat) CV measurements were done with a three electrode arrangement. The working electrode was soft glas coated platinum wire (diameter 1 mm). The platinum wire counter electrode was coiled around the glass tube of the working electrode. The pseudoreference electrode was a silver wire. All potential were referenced against the formal potentials of octamethylferrocene (C 2 2, -10 mv vs. Ag/Ag) or ferrocen (C 2 2, 460 mv vs. Ag/Ag). All CV measurements were done in dry C 2 2 under an Ar-atmosphere Bu 4 PF 6 als supporting electrolyte. Gas chromatography (Firma Perkin Elmer, Modell Auto System with a CP-SIL 8 AB column, l = 15 m, d i = 0.25 mm, d p = 1 0m)) using nitrogen as the carrier gas and FID detection. Quantification of the GC signals was made by referencing with authentic samples. 1 -MR und 13 C-MR-Spectra: uker WM 300 and AC-300 at 300 Mz or 75.5 Mz and a uker Avance at 500 Mz or 125.75 Mz, 31 P-MR-Spectra (uker AC 200, 80.96 Mz).
