All experiments were carried out under a dry, oxygen-free argon atmosphere using standard Schlenk techniques. Involved solvents were dried using MBraun SPS-800 (THF, DCM, toluene, acetonitrile, diethylether, hexane and pentane). Deionized water was degassed prior to use. Deuterated solvents were degassed and stored over molecular sieves in an argon-filled glovebox. NMR spectra were recorded on Avance-400 spectrometers at 25 °C if not stated otherwise. All values of the chemical shift are in ppm regarding the δ-scale. All spin-spin coupling constants (J) are printed in Hertz (Hz). To display multiplicities and signal forms correctly the following abbreviations were used: s = singlet, d = doublet, t = triplet, m = multiplet, br = broad signal. Assignments were confirmed using two-dimensional C-1 H NMR correlation experiments. IR-Spectra were recorded in an argon filled glovebox on a Shimadzu IRSpirit with QATR-S module and in transmission mode with a Specac "Omni-cell" with KBr plates and a 0.1 mm spacer. Elemental analyses were performed on an Elementar vario MICRO-cube elemental analyzer. X-ray data collection of the compounds was conducted with an Oxford Synergy using MO Kα radiation (λ = 0.71073 Å).
