Synthesis and crystal structures of palladium complexes based on α-amino-oximes derived from (R)-limonene and their application in allylic alkylation of 1,3-dioxo compounds
Coordination compounds Pd(L1)Cl2, Pd(L2)Cl2, and Pd(L3)Cl2 have been synthesized from optically pure α-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 α-amino-oxime ligands were then evaluated in the palladium-catalysed allylation of 1,3-dioxo compounds
