FOR 1175: Unconventional Approaches to the Activation of Dihydrogen

在瑞士和德国的两国合作中，该项目涉及氢化学的基本方面和发展，强调无金属和离子氢化催化的及时方面，这些催化与H-H键的异裂有关。近年来，氢化学作为一种清洁能源载体的潜在作用及其与化学储氢的联系变得越来越重要。选择了一种概念新颖的氢化学基础研究方法来解决氢转化的剩余化学谜题。几十年来，氢的研究主要集中在具有H2均裂特性的威尔金森过渡金属催化剂的开发上。这种化学的主要缺点是使用贵金属催化剂和偏爱与非极性不饱和分子反应。这些缺点被认为可以通过利用最近出现的氢化反应通过异裂解裂解H2来克服，这些氢化反应被累积地表示为离子氢化，并且是过渡金属或主族元素（无金属）催化的。本项目还研究了双氢转移同时发生的极性转移氢化反应。寻求氢化学的综合基本方法，包括离子氢化和极性转移氢化的发展，最好是催化形式，重点是无金属，非贵金属或非常有效的贵金属催化剂。对新型氢相关催化剂的广泛探索为瑞士和德国的合作建立了化学平台。结合双氢作为清洁未来能源载体的愿景，以及双氢在化学储氢材料中的反应性，这一双边合作项目具有相当大的社会意义。该项目希望有助于对二氢化学的最终深刻理解，探索极性和无金属氢以及氢相关催化剂的缺失方面。各自的新见解被认为为氢技术的未来化学发展奠定了基础。

In a binational Swiss-German cooperation this project addresses fundamental aspects of hydrogen chemistry and developments emphasising the timely aspects of metal-free and ionic hydrogenation catalyses proceeding with heterolytic splitting of the H-H bond. Hydrogen chemistry has recently gained importance in conjunction with its potential role as a clean energy carrier and its connection to chemical hydrogen storage. A conceptually new, basic research approach to hydrogen chemistry was chosen to solve the remaining chemical enigma of hydrogen transformations. For decades hydrogen research focussed mainly on developments of Wilkinson transition metal catalyses with the characteristics of a homolytic splitting of H2. Major drawbacks of this chemistry were the use of noble metal catalysts and the preference for reactions with unpolar unsaturated molecules. These drawbacks are thought to be overcome by utilisation of recently emerged aspects of hydrogenations splitting H2 by heterolysis, which are cumulatively denoted as ionic hydrogenations and are transition metal or main group element (metal-free) catalysed. Polar transfer hydrogenations, operating on the basis of simultaneously occurring double H transfers, are also studied in this project. A comprehensive fundamental approach to hydrogen chemistry is sought consisting of developments for ionic hydrogenations and polar transfer hydrogenations, preferably in catalytic form with emphasis on metal-free, non-noble metal or very efficient noble metal catalyses. A broad search for new hydrogen related catalyses builds the chemical platform for this Swiss-German cooperation. In conjunction with the vision of dihydrogen as a clean future energy carrier and the involvement of dihydrogen reactivity in chemical hydrogen storage materials, this bi-national collaborative project attains considerable social relevance. The project would like to contribute to an ultimate profound understanding of dihydrogen chemistry exploring the missing facets of polar and metal-free hydrogen and hydrogen related catalyses. Respective new insights are thought to lay the grounds for future chemical developments in hydrogen technology.
