摘要：

Complexes of palladium, nickel and manganese, with the chiral ligand (+)-(4'R)-2-(4'-ethyl-3',4'-dihydrooxazol-2'-yl)phenol HLOH were synthesized and characterized by H-1, P-31 NMR spectroscopy, magnetic susceptibility and including the crystal structure determinations of trans-[PdL2OH] and [PdCILOH(PPh3)]. The L-OH moiety is co-ordinated in a bidentate fashion in neutral, cationic and anionic complexes, rigid on the NMR time-scale. Monodentate O-co-ordinated complexes were obtained only in the presence of phosphines. The manganese complex [MnCIL2OH] showed little activity in the catalytic epoxidation of styrene. The first phosphinite oxazoline ligand L-OP was synthesized from HLOH. Neutral and cationic alkyl and allyl complexes of palladium with it were obtained and characterized. The cationic complexes showed dynamic behaviour.
