One of the most appealing research areas is the mechanistic understanding of multi-electron multi-proton processes, which is central in the activation of small molecules such as CO2 and H2O. In this line, we have discovered that well-defined cobalt coordination complexes based on the tacn moiety are highly efficient homogeneous catalysts for the reduction of water,[1-3] organic substrates[4] and CO2. Interestingly, the low valent cobalt intermediate also promotes the highly-challenging visible-light reductive radical cyclizations reactions from unactivated chloroalkanes, which open new avenues in photoredox catalysis. In the presentation, we will discuss the synergy between experiments and theory to gain insights into intermediates and the operative mechanisms.
