The experiments determining bond dissociation energies of the gaseous complexes show that the window of the stability of the gold(II) complexes is rather narrow. It is sufficient to prepare these complexes in the gas phase, but it remains a question, whether these complexes could be also studied in solution. In order to test this possibility, we performed cyclic voltammetry (CV) experiments in dichloromethane (DCM) and dimethylformamide (DMF) solutions. We have selected DCM, because it is non-polar non-coordinating solvent and thus the conditions are closest to the gas phase experiments (Figure & S77). Unfortunately, the terpy complexes were not soluble in DCM and therefore the comparison of all complexes was done in DMF. The reduction of the complexes with the terpy ligand is reversible, whereas the reduction of the complexes with the bipy ligand is irreversible. We have further tested, whether we could separate the two one-electron reduction steps by increasing the CV scanning rate. The only successful separation was achieved for the [(bipy)AuCl2] + complex (in DCM -Figure and in DMF -Figure ). With the increasing scanning rate, the reduction became partially reversible. This result suggests that the irreversibility is associated with the decomposition of the complex that is fast. We did not succeed in separation of the reduction steps for the bromide complexes which suggest that they decompose even faster than the chloride complexes.
