Накратко на български

Малки групи от 3 до 8 златни атома се изследват като катализатори за създаване на въглерод-въглеродни връзки. Разработването им помага за създаване на по-ефективни химически процеси с по-ниска консумация на енергия в индустрията.

Polynuclear Gold Catalysis

•What is the problem/issue being addressed? During the last decade, homogeneous gold catalysis has witnessed rapid growth for C–C bond forming reactions. Most of the gold catalysts used in these reactions were mononuclear complexes. Despite some pioneer work, the study of well-defined small gold clusters remains largely unexplored. In this project, we planned to prepare new types of highly electrophilic small gold clusters (3-8 Au atoms) with potentially enhanced catalytic properties that could have a significant impact in the advancement of the gold catalysis field and the development of more efficient and environmentally friendly synthetic methods. •Why is it important for society? One of the main challenges that the European chemical industry (one of the biggest in Europe) is facing nowadays is the reduction of the energy consumption of the chemical processes. Although the amount of energy consumed in 2012 was 16% less than in 1990, the fuel and power consumption of the EU chemical industry, including pharmaceuticals, amounted to 56.6 million tonnes of oil equivalent (TOE). The long-term objective of this project is to contribute to the development of low energy efficient procedures (lower reaction temperature, more efficient catalysts, and better yields), which could be adapted by the Chemical Industry, making the European economy more competitive and better aligned with the Horizon2020 growth strategy. Working in a new area of development could lead to discover breaking advances in catalysis, adding to excellence in the research European area and opening new opportunities for me and the future steps in my career. •What are the overall objectives? GOLDCLUSTER aims at advancing the field of gold chemistry. The major goal is to develop small polynuclear gold clusters as new superelectrophilic gold(I) catalysts and then explore their catalytic reactivity in organic transformations for the construction of molecular complexity using relatively simple starting materials.

Цел на проекта

During the last decade, homogeneous gold catalysis has witnessed rapid growth for C–C bond forming reactions mainly due to the soft carbophilic Lewis acid properties of gold complexes toward C–C triple bonds. Compared to Lewis acids and other transition metals, gold catalysts are very active under mild conditions, can tolerate moisture and oxygen and are compatible with diverse functional groups. Gold catalyzed tandem and multi-component reactions allow the efficient transformation of simple starting materials in complex molecules, which have been used for the synthesis of numerous biologically active targets. GOLDCLUSTER aims at advancing the field of gold chemistry by the development of new superelectrophilic small gold (I) clusters (Au3, Au6 and Au8). These complexes will be used as catalysts in the retro-Büchner reactions of cycloheptatrienes to form in situ gold carbenes, leading to the formation of complex molecules using milder conditions (lower reaction temperature, more efficient catalysts, and better yields). In addition, the new catalysts will also be tested in the catalytic activation of small molecules, such as methane. GOLDCLUSTER will contribute greatly to the advancement of gold chemistry by exploring new directions in the area and providing new tools to further enhance the development of efficient synthetic methods that could be later adapted by the Chemical Industry, making the European economy more competitive and better aligned with the Horizon2020 growth strategy.
