Furthermore, a base-free iron-based protocol is designed and optimized for the novel TH of ester compounds using EtOH as H2 source. In addition, the chemical activity of new single rhodium atoms on Al2O3 is explored. Using limonene as a model compound, only the terminal olefin was hydrogenated and the potential selective character of the catalyst is highlighted.
