  contains two Cu atoms bridged together by two chloride ligands and connected to one Ti atom by one CpPPh2 ligand and one μ-Cl ligand. Despite the short distances in the Ti−Cl−Cu bridges, notably in 2 and 4, the NMR spectra reveals evidence of fluxion in solution attributed to the lability of the μ-Cl ligands.

  The titane-ruthenium heterobimetallic compounds (p-cymene)[(eta(5)-C5H5)(mu-eta(5):eta(1)-C5H4(CH2)(m)PR2)TiCl2]RuCl2 4-6 have been revealed to be quite good catalysts for the addition of formic acid to 1-hexyne and phenylacetylene. These preliminary results led us to synthesize new tetrametallic complexes 10-12 via the reaction of the titanocene phosphanes 1-3 with the polymer [Ru(CO)(2)(mu-O2CH)](n). Their catalytic ability for the enol esters formation has been studied. (C) 2003 Elsevier Science B.V. All rights reserved.

  A new family of cationic Ti complexes 4' with a pendant phosphine of general formula [(CpCpTiOAr)-Ti-P][BPh4] (Cp = eta(5)-C5H5; Cp-P = eta(5)-C5H4(CMe2)PR2) has been prepared in four steps from 6,6-dimethylfulvene. These complexes were designed to behave as Ti based frustrated Lewis pairs (FLPs). The key synthetic step is a reduction oxidation sequence from [(CpCpTiClOAr)-Ti-P] complexes 3 using lithium phosphide salts as the reductants and ferricinium tetraphenylborate as the oxidant. Four complexes have been structurally characterized by X-ray diffraction and show elongated Ti-P bonds, above 2.60 angstrom. One complex (4b': OAr = 2,6-Me2C6H3; PR2 = PCy2) reacted with benzaldehyde to form a typical FLP activation product. Complex 4b' also reacted with 2 equiv of trans-chalcone to form a 10-membered Ti phosphonium macrocycle (6b') by extrusion of 6,6-dimethylfulvene.

  An unprecedented series of titanocene-gold bi- and trimetallic complexes of the general formula [[(eta(5)-C5H5)-(mu-eta(5):kappa(1)-C5H4(CH2)(n)PPh2)TiCl2](m)AuClx](q+) (n = 0, 2, or 4; m = 1, x =1, q = 0 or m = 2, x = 0, q = 1) have been prepared and characterized spectroscopically. The luminescence spectroscopy and photophysics of one of the compounds, [[(eta(5)-C5H5)-(mu-eta(5):kappa(1)-C5H4PPh2)TiCl2](2)Au]PF6, have been investigated in 2MeTHF solution and in the solid state at 77 and 298 K. Evidence for interfragment interactions based on the comparison of electronic band positions and emission lifetimes, namely, triplet energy transfer (ET) from the Au- to the Ti-containing chromophores, is provided. The cytotoxicity of the complexes was evaluated on A2780 ovarian cancer cells and on their cisplatin-resistant cell line A2780cisR; the compounds showed activity in the low micromolar range that was markedly more active than the corresponding titanocene-phosphine precursors [(eta 5-C5H5)(eta(5)-C5H4(CH2)(n)PPh2)TiCl2], cisplatin, and, for some of them, the gold analogue [(PPh3)AuCl]. In an attempt to draw preliminary structure activity relationships, cell uptake measurements and interaction studies with plasmid DNA and the model protein ubiquitin (Ub) have been undertaken on some of the compounds.

  The reaction of the titanocene monophosphines 1 and 2 with the dimer [(p-cymene)RuCl2](2) give the heterobimetallic compounds (p-cymene)[(eta(5)-C5H4)(mu-eta(5):eta(1)-C5H4PPh2)TiCl2]RuCl2 and (p-cymene)[(eta(5)-C5H4)(mu-eta(5):eta(1)-C5H4CH2CH2PPh2)TiCl2]RuCl2, respectively. Both structures have been confirmed by X-ray diffraction. By using same procedure, the synthesis of a trimetallic complex Ru-Ti-Ru has been achieved. (C) 2000 Elsevier Science S.A.
