    preformed Pd(II) complexes 14, 15, 18 and 19 were tested as catalyst for the Heck coupling reaction in water. The influence of the oligoether and benzyl substituents on N atoms and CH3-substituents on the 5,6-positions of benzimidazole frame were investigated under the same conditions in the Heck coupling reaction. In situ formed catalysts showed better conversions than the isolated Pd(II) complexes.

    Platinum(IV) metallacrown ethers [PtBr2Me2 im(CH2CH2O)(x)CH(2)CH(2)m}] (im = imidazol-1-yl; x = 2-5, 7; 3-7) and [PtBr2Me2 bim(CH2CH2O)(x)CH(2)CH(2)bim}] (bim = benzimidazol-1-yl; x = 1, 2, 5, 7; 9-12) were synthesized via the reaction of [(PtBr2Me2)(n)] with the appropriate alpha,omega-bis(imidazol-1-yl) or alpha,omega-bis(benzimidazol-1-yl) polyether. Reactions with 1,2-bis(imidazol-1-yl)ethane, bis(2-(imidazol-lyl)ethyl) ether, or 1,2-bis(benzimidazol-1-yl)ethane yielded the dinuclear complexes [(PtBr2Me2)(2)im(CH2CH2O)(x)CH(2)CH(2)im}(2)] (x = 0, 1; 1, 2) and [(PtBr2Me2)(2)mu-bimCH(2)CH(2)bim}(2)] (8), respectively. In addition, the diiodo complex [PtI2Me2im(CH2CH2O)(2)CH(2)CH(2)im}] (13) was prepared from the reaction of [PtMe2(cod)] with I-2 in the presence of im(CH2CH2O)(2)CH(2)CH(2)im. Characterization by microanalysis and NMR spectroscopy, as well as X-ray crystal structure analysis of several of the metallacrown ethers (3, 5, 9 and 10) and dinuclear complexes (2 and 8), is described. The ability of the larger metallacrown ethers (5-7, 11 and 12) to act as hosts to either dibenzyl- or di-n-butylammonium ions is investigated in solution (NMR and ESI-MS). Finally, several of these metallacrown ethers were found to possess in vitro antitumor activity on three tumor cell lines (liposarcoma, A549 and 518A2). The activity of these complexes, all of which were found to induce apoptotic cell death, is discussed relative to their structure and the findings of platinum uptake studies.
