The higher apparent activity, aligning with the stability of the cation, positions DiCl as a promising contender for the efficient activation of CO2. However, a more comprehensive analysis involving detailed GC and liquid analysis is necessary to investigate the potential formation of other products, when using a DiCl solution. Notably, the LSV results reveal a deviation in the apparent slope of the current-potential profile when compared to the MM, TM, DiPh and DiMeOPh cations investigated in this study. This observation prompts us to consider alternative mechanisms that could be contributing, possibly linked to the heightened acidic nature of the cation. Figure 4.9.
