Synthesis of Pd(II) coordination complexes of (S)-4-isobutyl-2-methyl-2-oxazoline and (S)-2-(2,2-dimethylpropyl)-4-isopropyl-2-oxazoline

Two new enantiopure oxazolines, (S)-4-isobutyl-2-methyl-2-oxazoline (HL-1) and (S)-2-(2,2-dimethylpropyl)-4-isopropyl-2-oxazoline (HL-2), reacted with Pd(OAc)2 followed by treatment with LiCl to form the corresponding coordination complexes PdCl2(HL)2 with no traces of cyclopalladated derivatives PdCl2L2.
