    • - adduct of the dimer. Mass spectra were recorded on a Finnigan MAT90 spectrometer using an electrospray source (Finnigan) at an acceleration potential of +5000 V and an infusion pump E540101 (TSE) (Harvard Apparatus). The solution of 2 in methanol was infused through a 75 μm fused silica capillary at a flow rate of 0.5 μL/min. 89 scans were recorded in the range of m/z 400-1200 (scan speed 8.27 s/scan).
