Objective ChemCatSusDe addresses some of the industrial and economical issues of our society: fossil fuel depletion, use of renewable resources derived from the biomass, environmentally friendly chemistry for a sustainable future. At its core lies the versatility of complexes of zinc, magnesium, calcium, strontium and barium (the so-called bio-metals): green catalysts able to perform both the polymerisation of cyclic esters and highly atom-efficient hydroelementation reactions will be designed.The objectives defined by the researcher and the host institution in Rennes are:- Synthesis of well-defined complexes of the large alkaline-earth (Ca, Sr, Ba). The coordination chemistry of these metals in the presence of chelating, mono-anionic ligands will be studied. Owing to the extreme oxophilic nature of these elements, these catalytic precursors are expected to display excellent activities. The same synthetic strategies will also be extended to the preparation of complexes of the smaller zinc and magnesium, which display an excellent compromise between stability and catalytic activity- Use of these complexes for the catalytic immortal ring-opening polymerisation of cyclic monomers derived from renewable bioresources for the production of biocompatible and/or biodegradable polymers. All catalysts will be used for the polymerisation of lactide and monomers such as morpholinediones and b- or g-valerolactones- Hydroelementation of terminal alkenes catalyzed by heteroleptic amido-alkaline-earth complexes. Catalysts for the 100% atom-efficient hydrosilylation, -phophination and -amination of unsaturated substrates will be prepared- Study of the stability and reactivity of the targeted heteroleptic complexes by theoretical calculations: the design of catalytic systems will be elaborated and/or optimized according to preliminary calculations or those based on experimental structural data.- Development of long-term collaborations between the host and return institutions Fields of science natural scienceschemical sciencesinorganic chemistrytransition metalsnatural scienceschemical sciencesinorganic chemistryalkaline earth metalsnatural scienceschemical sciencespolymer sciencesnatural scienceschemical sciencescatalysisnatural sciencesmathematicsapplied mathematicsmathematical model Programme(s) FP7-PEOPLE - Specific programme "People" implementing the Seventh Framework Programme of the European Community for research, technological development and demonstration activities (2007 to 2013) Topic(s) FP7-PEOPLE-2010-IIF - Marie Curie Action: "International Incoming Fellowships" Call for proposal FP7-PEOPLE-2010-IIF See other projects for this call Funding Scheme MC-IIFR - International incoming fellowships (Return phase) Coordinator CHANGCHUN INSTITUTE OF APPLIED CHEMISTRY - CHINESE ACADEMY OF SCIENCE - CIAC Address Ren min street - chaoyang district 5625 130022 Changchun China See on map Activity type Research Organisations Administrative Contact Dongmei Cui (Prof.) Links Contact the organisation Opens in new window Website Opens in new window EU contribution No data
