This project addresses fundamental issues in catalysis for carbon dioxide reactivity with glycerol to carbonic esters. Two waste chemicals are, therefore, involved as renewable feedstocks for making high-value products. The perspective is to get an entry for developing CO2-neutral reactions of promising development and increasing importance for the future. Emphasis is put on molecular catalyst design and catalytic reactor optimization to promote the reaction and tune selectivity for glyceric carbonates. To achieve this goal three partners (CNRS, Dortmund University and New University of Lisbon) will share their complementary competences in close collaboration. The new trans-national cooperation will benefit from tightly linked methodologies in molecular catalysis: precatalyst synthesis and characterization, high-pressure catalytic reaction, reaction kinetics, mechanistic studies, reactor technology, and fluid phase thermodynamics. Coordination chemistry of glycerol-based ligands targeting the reactivity with carbon dioxide and relevant mechanistic studies in correlation with catalytic activity have been unexplored. The knowledge acquired during this project will set the rules of metal binding to polyols and CO2 for catalysis. Metal-oxygen bonds are the new key players for oxygenated feedstock transformation, just as metal-carbon bonds dictate the pathways to C-C couplings to produce oligomers and polymers from olefin feedstock. The know-how acquired in reactor technologies and fluid phase thermodynamics will provide the basic requirements for the catalytic process to be performant.

该项目解决了二氧化碳与甘油反应催化生成碳酸酯的基本问题。因此，两种废弃化学品被用作制造高价值产品的可再生原料。其前景是获得开发二氧化碳中和反应的机会，该反应具有良好的发展前景，并且对未来的重要性日益增加。重点放在分子催化剂设计和催化反应器优化上，以促进反应并调整碳酸甘油酯的选择性。为了实现这一目标，三个合作伙伴（法国国家科学研究中心、多特蒙德大学和里斯本新大学）将密切合作，分享互补能力。新的跨国合作将受益于分子催化领域紧密相连的方法学：催化剂前体合成和表征、高压催化反应、反应动力学、机理研究、反应器技术和液相热力学。针对与二氧化碳的反应性的甘油基配体的配位化学以及与催化活性相关的相关机制研究尚未被探索。该项目期间获得的知识将制定金属与多元醇和二氧化碳结合的催化规则。金属-氧键是含氧原料转化的新关键参与者，就像金属-碳键决定了从烯烃原料生产低聚物和聚合物的C-C偶联途径一样。在反应器技术和液相热力学方面获得的专业知识将为催化过程的性能提供基本要求。
