trans-isomers. The 13C 1H} NMR and 1H NMR spectra of 2a - 4c have been analysed, the trans-structure of 4c could be assigned to the predominant isomer. The X-ray structural analysis of 4c (triclinic, space group Pl̅) reveals a trans-square planar coordination at palladium with an antiperiplanar arrangement of the bulky tBu substituents at the phosphorus atoms.
