Periodic Reporting for period 4 - UNBICAT (Unconventional Bifunctional Catalysts)
Okres sprawozdawczy: 2020-03-01 do 2021-08-31
Over recent years in this project we have managed to consolidate two areas in the research group concerning the use of sustainable processes, in the field of photocatalysis and organocatalysis. Thus, we have described new activation processes for silylated compounds, which constitutes an alternative to the traditional methods, and also with very good enantiomeric excesses. While in the second part of the project, we have used new bifunctional organocaphotocatalysts for different reactions, such as aldehyde alkylations, cycloaddition reactions, among many others. Therefore, thanks to this project we have developed an arsenal of different methodologies, which will allow our group and other research groups new possibilities within asymmetric catalysis.
The UNBICAT project has obtained very good results both in quantity and quality of the publications obtained, giving rise to relevant results, published in prestigious journals such as Nature Communs, Angewandte Chem., J. Am. Chem. Soc, Chemical Sciences, among others (for the completed list, see www.uam.es/jose.aleman). In addition, the results throughout these years have been disseminated in different prestigious national and international forums. Some additional activities of our group

In the last years, our research group has been developing new organocatalytic processes in two main areas and covalent catalysis. For example, we have contributed to the activation of silyldienol ethers, obtaining interesting Bayllis-Hillman and Rauhut-Currier type products, as well as remarkable nitrogen additions applied to the synthesis of aminoacids or the development of inverse-electron demand aza-Diels-Alder reactions. In the field of photocatalysis, we have contributed with the development of new photocatalysts, such as acridinium-type salts, bifunctional aminocatalysts, platinum-bearing systems, or diamine-derivatives for [2+2] cycloadditions. In addition, we have studied and described new photocatalytic processes, such as ring expansion reactions, tandem processes, alkylations, or heterocyclic syntheses. During these investigations, the degradation of the photocatalyst, and in occasions the required high catalytic loadings, prompted us to explore new horizons in our research, such as the use of materials. Thus, in the catalytic material field, we have focused on the application of our knowledge in photocatalysis and organocatalysis for its implementation in heterogeneous systems. Thus, we have incorporated platinum photocatalytic centers in mesoporous silica materials (J. Catal. 2019, 374), or Covalent Organic Frameworks (COF) using a novel strategy (Applied Catal. B, 2020, 119027). Our interest was also related to the use of COF with heterobimetallic structures (ACS-Catal, 2021, 11, 12344), or the incorporation of organic photocatalysts to mesoporous materials (J. of Materials Science, 2022, 103, 134) and carbon nanotubes (ACS Appl. Mater. Interfaces 2021, 24877). These initial explorations on catalytic materials, has given us a practical idea of the advantages and limitations of each class of materials (COF, nanotubes, and mesoporous silica).
