The invention relates to a coordination complex system for chemically converting a substrate comprising a non-protein ligand having a first building block with at least one functional group and at least one donor moiety, which donor moiety is complexed to a metal selected from a transition metal and lanthanide or an organometallic precursor thereof, characterized in that the ligand further comprises at least one second building block not having a donor moiety and having at least one functional group that is complementary to the at least one functional group of the first building block, wherein the first building block and the second building block are non-covalently bonded through their functional groups. These coordination complex systems are used as a catalyst for chemical reactions such as hydroformylation, hydrogenation, transfer hydrogenation, hydrocyanation, polymerization, isomerization, carbonylation, cross-coupling, metathesis, CH-activation, allylic substitution, aldol condensation, and Michael addition, preferably to obtain chiral compounds.
本发明涉及一种用于底物化学转化的配位络合物体系,该体系包括一个非蛋白配体,该配体具有一个带有至少一个官能团的第一结构单元和至少一个供体分子,该供体分子与选自过渡金属和镧系元素的金属或其有机金属前体络合、其特征在于,配体还包括至少一个不具有供体分子的第二结构单元,该第二结构单元具有至少一个与第一结构单元的至少一个官能团互补的官能团,其中第一结构单元和第二结构单元通过它们的官能团非共价键合。这些配位复合物体系可用作化学反应的催化剂,如加氢甲酰化、氢化、转移氢化、氢氰化、聚合、异构化、羰基化、交叉偶联、偏合成、CH-活化、烯丙基取代、醛醇缩合和迈克尔加成,最好是用于获得手性化合物。
