the Rh center imparted by the rigid PTN framework. The complexes were tested as catalysts for (biphasic) olefinhydroformylation and regioselective CC bond reduction under transfer hydrogenation conditions, together with acetophenone hydrogenation. DFT calculations on simplified models helped to assess the bonding properties within the complexes and to determine the amount of cage strain that accompanies

Abstract New palladium(II) complexes containing the watersoluble aminophosphine PTN ligand (PTN = 7-phospha-3,7-dimethyl-1,3,5-triazabicyclo[3.3.1]nonane) in 1:1 and 1:2 ratio Pd/PTN ligand, respectively, were prepared and fully characterised by mono and bidimensional 31 P, 1 H and 13CNMR techniques showing that PTN can adopt both κ 1 - P and κ 2 - P , Ncoordination modes. The complexes with Pd/PTN
Reductive cleavage of the methylphosphoniatriazaadamantane cation by sodium in liquid ammonia affords the new bicyclic ligand (MeP)(CH2)5N2(NMe) whose structure has been determined from crystals of its 1 : 1 complex with AuCl.

A series of compounds of the general formula [M(eta(6)-arene)(ptn)Cl]X (M = Ru, Os; arene = p-cymene, benzene, toluene, hexamethylbenzene; ptn = 3,7-dimethyl-7-phospha-1,3,5-triazabicyclo[3.3.1]nonane; X = Cl-, BF4-) have been prepared and characterized spectroscopically. X-ray diffraction was additionally used to characterize four of the complexes in the solid state. The hydrolysis of the compounds was studied, and their cytotoxicity was evaluated in A2780 ovarian cancer cells and found to be comparable to that of known RAPTA complexes based on 7-phospha-1,3,5-triazatricyclo[3.3.1.1]decane (pta). The reactivity of the complexes toward double-stranded oligonucleotides and the model protein ubiquitin was investigated using Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR-MS) and gel electrophoresis, demonstrating a strong preference for the formation of covalent adducts with the protein. Correlations among compound structure, hydrolysis, biomolecular interactions, and cytotoxicity are established.

Suggested is a process for the manufacture of unsaturated fatty acid alkyl esters or glycerides having a total content of C 18:1 of about 30 to about 80 Mol-% by partial hydrogenation of unsaturated fatty acid esters having a total content of (C18:2+C18:3) of at least 65 Mol-%—calculated on the total amount of C18 moieties in the ester—which is characterised in that the hydrogenation is conducted in an aqueous/organic two phase system in the presence of a water soluble catalyst consisting of a Group VIII metal and a hydrophilic ligand.
