Project description
Unlocking the overlooked potential of bismuth as a catalyst for organic synthesis
Industrial homogeneous catalysis based on the use of transition metal catalysts is indispensable for the construction of organic compounds. Within the EU-funded Let-it-Bi project, researchers aim to revolutionise the field of organic synthesis by going into a little-used corner of the periodic table to develop a new set of highly active and sustainable catalysts – bismuth. This overlooked redox system can be used in small molecule activation and olefin functionalisation. Bismuth is abundant, inexpensive, and has a remarkably low toxicity. With these attributes, the project is increasingly attracted to bismuth, aiming to discover novel chemical reactions for organic synthesis, which have remained elusive to date.
Objective
Homogeneous catalysis based on transition metals has become an indispensable strategy in the development of efficient methodologies for organic synthesis, finding application in a wide variety of processes across the chemical sciences. Inspired by the wealth of reactivity in this area, we present a proposal that departs from transition metal catalysis and aims at unlocking the potential of bismuth (Bi) as a sustainable catalyst, unravelling novel and unknown catalytic redox processes for organic chemistry. The main goal of this project is to translate the unique properties traditionally associated to transition metals to a main group element. Let-it-Bi is a quest to disclose the remarkable potential of a commonly overlooked element of the periodic table such as bismuth, in the field of catalysis and organic synthesis. Being an earth abundant, non-toxic and inexpensive element, bismuth represents an excellent candidate to be explored in catalysis and to study its fundamental reactivity. In the first part of this proposal, we describe the design of a novel Bi(III)Bi(V) redox cycle towards the formation of synthetically relevant and challenging CC, CHalogen, CN and CO bonds. The last part proposes the expansion of this concept to an unprecedented Bi(I)Bi(III) redox cycle. Such a unique redox system will find application in the activation of small molecules (H2, NH3, BH and SiH bonds) for the functionalization of simple and largely available olefins. In addition to provide a solution to the price, toxicity and environmental issues associated to transition metal-based transformations, this proposal aims at the exploration of uncharted territories in the area of homogeneous catalysis; thus discovering and providing novel reactivities for organic synthesis which remained elusive to date. Noteworthy, preliminary results accompany both parts demonstrating the feasibility of the proposed research.
