Note: The functionalization of C=C and C–X bonds (X = I, Cl, Br, and H) is fundamental in organic chemistry for making carbon-carbon bonds or for introducing molecular complexity. Chemists have traditionally relied on precious metals catalyst such as palladium, platinum, and iridium to facilitate these transformations. Some of these metals, if not all of them, are one of the rarest on earth, leading to increasingly high prices and uncertainty in future supply chains. As their availability continues to decline it is important to address the scarcity of these metals to secure a sustainable future. One solution is to develop new technologies that allow one to substitute the precious metal catalysts for those that are abundantly available (e.g., iron), without sacrificing on performance and selectivity. Because of the fundamental differences between the properties of iron (one-electron chemistry) and the second/third-row transition metals (two-electron chemistry), this approach has shown to be a daunting task. If, however, it could be shown that iron could reliably engage in two-electron chemistry, then the reactivity of precious metals could be unlocked for iron. Through bespoke ligand design we will attempt to unlock this two-electron chemistry and apply it to three of the most common reactions in organic synthesis; (i) cross-coupling, (ii) alkene metathesis, and (iii) C–H bond functionalization. By relying on a distinct two-electron mechanism, a treasure trove of possibilities for selective bond forming reactions is generated. Overall, this work is expected to result in new avenues in earth-abundant metal catalysis and provide new methodologies to construct ever important C-C and C-N that can be used to induce molecular complexity.
