Due to steric promotion of CH bond activation, the direct ortho-palladation of (S)-4-tert-butyl-2-phenyl-2-oxazoline using Pd(OAc)2 in AcOH provided (S,S)-di-μ-acetatobis-[2-(2-(4-tert-butyl)oxazolinyl)phenyl-C,N]dipalladium(II) (2) in an excellent yield. This complex was converted into its corresponding μ-chloro analog (3) using LiCl in acetone. Dimer 3 reacted with PPh3 to furnish the phosphane mononuclear derivative 4. The structure of the dimer complex 3 was confirmed by X-ray diffraction analysis.
