Накратко на български

Нови катализатори, съчетаващи преходни метали и „фрустрирани двойки Луис“, се тестват за активиране на малки молекули. Те помагат за подобряване на химическото производство и развитието на устойчива химия, енергийни системи и здравеопазване.

Bond Activation and Catalysis by Transition Metal Frustrated Lewis Pairs

This proposal has focused on developing a novel approach in the hot field of cooperative catalysis by merging fundamental concepts of main group and transition metal chemistry. Catalysis is critical to the delivery of future growth in the manufacturing sector, with catalytic processes generating around €1,000 Bn in products world-wide. Thus, the development and fundamental understanding of innovative new catalyst systems, such as the ones investigated in this proposal, has clear, direct and long-term benefits to the chemical manufacturing sector and to the broader knowledge-based economy. Moreover, catalytic science is a multidisciplinary and significant enabling discipline crucial to the advance of many priority areas such as the search of future energy systems, solar technologies, sustainable chemistry, synthetic biology or healthcare. Nature catalytic designs outperform most synthetic approaches in terms of activity, selectivity or substrate scope, while relying on cooperative architectures in which neighbouring set of atoms crucially assist the metal to achieve a certain catalytic transformation. A paradigmatic approach in the area of synthetic cooperative chemistry is the development of Frustrated Lewis Pairs (FLPs), in which sterically encumbered combinations of Lewis acid/base (LA/B) couples are not quenched, but act cooperatively to activate a wide variety of small molecules. Drawing on this theme, the overall objective of this proposal was combining the rich chemistry of transition metals with the powerful reactivity offered by FLP systems by designing TM-FLPs after substituting at least one LA/B component by a transition metal and then demonstrating its usefulness for the activation and functionalization of small molecules.

Цел на проекта

Catalysis is critical to the delivery of future growth in the manufacturing sector: ca. 75% of all chemicals currently require catalysts at some stage in their manufacture, with catalytic processes generating €1,000 Bn in products world-wide. This proposal targets a step-change in homogenous catalysis by approaching it from a new perspective. Frustrated Lewis Pairs (FLPs) are among the most promising new avenues for the development of future catalysts and offer important advantages in the context of sustainability. Thus the young field of FLP chemistry has experienced an enormous expansion since its founding discoveries one decade ago. However, this rapid development contrasts with the very limited number of examples in the literature in which one of the Lewis acid/base (LA/B) components is based on a transition metal. The current proposal aims to combine the rich chemistry of transition metals (ultimately Earth-abundant elements) with the powerful reactivity offered by FLP systems by substituting one of its LA/B components by a transition metal. The extraordinary structural diversity of transition metals, along with the rich variety of elementary reactions that take place over those centres, are attributes that will extend the usefulness of FLPs far beyond the present (mainly) hydrogenation reactions and should allow developing new catalytic processes unreachable for current homogeneous catalysts. The possibilities are as unexplored as unlimited. We aim to exploit Pt and Au systems, for which preliminary results are available in the host group and will give high confidence of short-term success. Subsequently we will build on the key principles so established to expand our approach to ecologically more benign first-row transition metals. The potential in bond activation and catalysis of the resulting transition metal FLP systems will be explored with the ultimate goal of developing novel catalytic cycles of industrial relevance.
