Synthesis and crystal structures of palladium complexes based on alpha-amino-oximes derived from (R)-limonene and their application in allylic alkylation of 1,3-dioxo compounds

International audience; Coordination compounds Pd(L1)Cl2, Pd(L2)Cl2, and Pd(L3)Cl2 have been synthesized fromoptically pure α-amino-oxime ligands L1–L3 based on (R)-limonene. Structures of the new palladiumcomplexes are characterized and described by NMR spectroscopy and X-rays. These α-amino-oximeligands were then evaluated in the palladium-catalysed allylation of 1,3-dioxo compounds.; Les complexes Pd(L1)Cl2, Pd(L2)Cl2, et Pd(L3)Cl2 ont été synthétisés à partir des ligands α-amino-oxime L1-L3 issus du (R)-limonene. Ces nouveaux complexes de palladium ont été carracté-risés par RMN et diffraction aux rayons X. Les ligands α-amino-oxime associés à des précurseurs depalladium ont été évalués sur des réactions d’alkylation allylique.
