Two isomeric bis(phosphane) palladium chloride complexes with functional catechol phosphane ligands were immobilised on different specimens of TiO 2 . The solid materials were characterised by 31 P NMR spectroscopy both when dry and as suspensions in various solvents. The NMR spectroscopic studies demonstrated that the resistance towards leaching varies strongly with the nature of the carrier material and that the surface‐bound complexes may become detached from the support in certain circumstances in the presence of solvents that are sufficiently polar or contain reactive components such as amines.(© Wiley‐VCH Verlag GmbH & Co.
