Аннотация:Two novel oxazoline-derived palladacycles bearing an endo- or exo-C=N bond were prepared by direct ortho-palladation of (R)-2,4-diphenyl- or (R)-2-methyl-4-phenyl-2-oxazolines, respectively. The structures of the palladacycles’ dimeric forms and corresponding
mononuclear PPh3-derivatives were confirmed by IR, 1H, 13C and 2D NMR spectroscopy. An X-ray diffraction study of the l-chloro-dimeric cyclopalladated derivative of (R)-2,4-diphenyl-2-oxazoline proved the endo structure of the palladacycle.
