Over the last decade, metal/ligand cooperation (MLC) has attracted huge attention in homogeneous catalysis. Thanks to the synergy between the transition metal and one of its ligands for the activation of the substrates, extraordinary improvements in efficiency and selectivity can be achieved.1 Pincer complexes of transition metals play a prominent role in this domain, and our group has contributed to the field with a family of original SCS pincer ligands based on an indene skeleton bearing two coordinating P=S side-arms. Remarkable results have been obtained in Pd and Pt catalyzed cyclisation processes involving the formation of C-O/C-N & C-C bonds and thorough mechanistic investigations have supported metal-ligand cooperation. We are currently working on a new family of PNS pincer ligands deriving from the quinoline moiety. We have evidenced two different sites of non-innocent behavior (through dearomatization and across the M-S bond). Proofs of concept for their application in MLC catalysis with Pd complexes have also been obtained in heterofunctionalization processes involving Eδ+-Hδ- bond activation (E = Si, Ge) thanks to Pd-S cooperation.3 Objectives. This PhD aims at expanding and exploiting the structural diversity of such complexes, with variations of both the non-innocent ligand and the transition metal (Ru as well as abundant 3rd row transition metals such as Fe and Mn). The corresponding complexes will be thoroughly characterized and their non-innocent behavior towards Xδ--Hδ+ (X = C, O, N …) and Eδ+-Hδ- (E = Si, Ge, B …) bond activation will be investigated. Ultimately, this new type of MLC will be leveraged in catalytic transformations. In summary, this proposal is at the cross point of organometallic chemistry and catalysis. It involves the design of non-innocent ligands, their coordination to TM, reactivity studies towards small molecule activation and applications in MLC-catalysis. 參考文獻: [1] Milstein, D. Angew. Chem.
