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

Coordination compounds Pd(L1)Cl$_{2}$, Pd(L2)Cl$_{2}$, and Pd(L3)Cl$_{2}$ have been synthesized from optically pure $\alpha$-amino-oxime ligands L1–L3 based on $(R)$-limonene. Structures of the new palladium complexes are characterized and described by NMR spectroscopy and X-rays. These $\alpha$-amino-oxime ligands were then evaluated in the palladium-catalysed allylation of 1,3-dioxo compounds

Synthesis of C4 chain glyceryl ethers via nickel-catalyzed butadiene hydroalkoxylation reaction

International audienceThe catalytic hydroalkoxylation of butadiene with glycerol has been performed for the first time thanks to the use of nickel catalysts and an appropriate solvent. Optimization of the reaction conditions allowed obtaining 100% glycerol conversion into a mixture of glyceryl mono- and dibutenyl ethers. The experimental protocols used involved batch experiments or continuous feeding of butadiene at atmospheric pressure. The reaction has then been scaled up to produce multigrams of each pure monoethers and diethers according to simple decantation/distillation procedures. The ethers were further hydrogenated to their corresponding alkyl glyceryl ethers
