Platinum and ruthenium complexes of new long-tail derivatives of PTA (1,3,5-triaza-7-phosphaadamantane): Synthesis, characterization and antiproliferative activity on human tumoral cell lines

The alkylation of PTA, (1,3,5-triaza-7-phosphaadamantane), with long chain alkyl iodides produced the novel ionic derivatives (PTAC12H 25)I, (PTAC16H33)I and (PTAC18H 37)I. Anion exchange gave the PF6- analogs (PTAC12H25)PF6, (PTAC16H 33)PF6 and (PTAC18H37)PF 6. The new phosphines were characterized by ESI-MS, elemental analysis, 1H, 13C, and 31P NMR spectroscopy and their coordination ability was investigated towards Pt(II) and Ru(II) cores. Complexes cis-[PtCl2(PTAR)](PF6)2 (1-3) and [CpRuCl(PPh3)(PTAR)]I (5-7) have been isolated and characterized. Antiproliferative activity, given as estimated IC50, was tested for each complex against appropriate human tumoral lines (T2, SKOV3 and SW480) in comparison with cisplatin, with the parent complexes [CpRuCl(PPh 3)(PTA)] and [CpRuCl(PPh3)(PTAMe)]I and with the free ligands.

Novel structural rearrangements induced by metal-metal interactions in ruthenium(II) ruthenocenyl- and (pentamethylruthenocenyl)acetylide complexes, RcC?CRuL2(eta5-C5R5) and Rc?C?CRuL2(eta5-C5R5)

The reaction of RcC?CH [Rc = (eta5-C5H5)Ru(eta5-C 5H4)] with RuCIL2(eta5-C5R5) [R = H or Me; L2 = 2PPh3 or Ph2PCH2CH2PPh2 (dppe)] in the presence of NH4PF6 and subsequent treatment with base gave Ru(II) ruthenocenylacetylide complexes RcC?CRuL2(eta5-C5R5) in good yields. In a similar manner, the pentamethylruthenocene analogues, Rc?C?CRuL2(eta5-C5R5) [Rc? = (eta5-C5Me5)Ru(eta5-C 5H4)], were also prepared. Cyclic voltammograms of the complexes showed two reversible one-electron-oxidation processes, consisting of the processes [Ru(II)Ru?(II] to [Ru(III)Ru?(II] and then to [Ru(III)Ru?(III)]. Chemical oxidation of the complexes induced novel structural rearrangement. The two-electron oxidation of complex RcC?CRu(PPh3)2(eta5-C5H 5) afforded a kind of allenylidene complex, a cyclopentadienyl-idenethylidene complex, [(eta5-C5H5)Ru{mu-eta 6:eta1-C5H4C=C}Ru(PPh 3)2(eta5-C5H5)] 2+, in 90% yield. The one-electron oxidation of Rc?C?CRu(PPh3)2(eta5-C 5H5) gave the vinylidene complex (Rc?CH=C)Ru(PPh3)2(eta5-C 5H5) in 62% yield, while the two-electron oxidation led to the fulvene-vinylidene complex [(eta6-C5Me4CH2)Ru{mu-eta 5:eta1-C5H4CH=C}Ru(PPh 3)2(eta5-C5R5)] 2+ by an intramolecular hydrogen transfer in 59% yield.

Organoruthenium(ii) nucleoside conjugates as colon cytotoxic agents

Eleven ruthenium-nucleoside conjugates with the general formula [(eta5-C5H5)Ru(PP)L][PF6] (PP = 1,2-bis(diphenylphosphino)ethane (Dppe), 2PPh3, and L = 3-N-(p-cyanobenzyl)thymidine derivative ligand) are reported. Both [(eta5-C5H5)Ru(Dppe)NC-R]+ and [(eta5-C5H5)Ru(PPh3)2NC-R]+ scaffolds exhibit remarkable stability towards hydrolysis. Compounds show high cytotoxicity in HCT116 colon cancer cells, with IC50 values down to 1.0 muM. Uptake competition experiments with 2?-deoxyadenosine revealed its cellular absorption to be independent of nucleoside transporters.

Monomeric and dimeric ruthenium-TCNQ complexes containing phosphine ligands (TCNQ= 7,7,8,8-tetracyanoquinodimethane)

Treatment of [Ru(CO)2(PPh3)2(THF)2](BF 4)2, with LiTCNQ (TCNQ = 7,7,8,8-tetracyanoquinodimethane) in dichloromethane at reflux resulted in the formation of [Ru(CO)2(PPh3)2(TCNQ)]BF4 (1). The synthesis of the carbonylhydride compound [RuH(CO)(PPh3)2(TCNQ)]2 (2) was carried out by reaction of RuHCl(CO)(PPh3)3 and TCNQ or from [RuH(CO)(PPh3)2(CH3CN)2]PF 6 and LiTCNQ. The preparation of compounds with diphosphines [Ru(dppe)2(TCNQ)]2TCNQ(ClO4) (3) and [Ru(dppm)3 TCNQ]ClO4 (4) is also described. In all cases substitution reactions of labile ligands occurred with formation of compounds with sigma-coordinated TCNQ. From IR, UV-vis, 1H and 31P NMR spectroscopy and FAB mass spectrometric determinations, monomeric and dimeric compounds are proposed.

Quadratic and cubic hyperpolarizabilities of nitro-phenyl/-naphthalenyl/-anthracenyl alkynyl complexes

1-Nitronaphthalenyl-4-alkynyl and 9-nitroanthracenyl-10-alkynyl complexes [M](CC-4-C10H6-1-NO2) ([M] = trans-[RuCl(dppe)2] (6b), trans-[RuCl(dppm)2] (7b), Ru(PPh3)2(eta5-C5H5) (8b), Ni(PPh3)(eta5-C5H5) (9b), Au(PPh3) (10b)) and [M](CC-10-C14H8-9-NO2) ([M] = trans-[RuCl(dppe)2] (6c), trans-[RuCl(dppm)2] (7c), Ru(PPh3)2(eta5-C5H5) (8c), Ni(PPh3)(eta5-C5H5) (9c), Au(PPh3) (10c)) were synthesized and their identities were confirmed by single-crystal X-ray diffraction studies. Electrochemical studies and a comparison to the 1-nitrophenyl-4-alkynyl analogues [M](CC-4-C6H4-1-NO2) ([M] = trans-[RuCl(dppe)2] (6a), trans-[RuCl(dppm)2] (7a), Ru(PPh3)2(eta5-C5H5) (8a), Ni(PPh3)(eta5-C5H5) (9a), Au(PPh3) (10a)) reveal a decrease in oxidation potential for ruthenium and nickel complexes on proceeding from the phenyl- to naphthalenyl- and then anthracenyl-containing bridge. HOMO ? LUMO transitions characteristic of MCC-1-C6H4 to 4-C6H4-1-NO2 charge transfer red-shift and gain in intensity on proceeding to the ruthenium complexes; the low-energy transitions have increasing ILCT character on proceeding from the phenyl- to naphthalenyl- and then anthracenyl-containing bridge. Spectroelectrochemical studies of the Ru-containing complexes reveal the appearance of low-energy bands corresponding to chloro-to-RuIII charge transfer that red-shift on proceeding from the phenyl- to naphthalenyl- and then anthracenyl-containing bridge. Second-order nonlinear optical (NLO) studies at 1064 nm employing ns pulses and the hyper-Rayleigh scattering technique reveal an increase in quadratic optical nonlinearity upon introduction of metal to the precursor alkyne to afford alkynyl complexes and on proceeding from ligated-gold to -nickel and then to -ruthenium for a fixed alkynyl ligand. Quadratic NLO data of the gold complexes optically transparent at the second-harmonic wavelength reveal an increase in betaHRS on proceeding from the phenyl- to the naphthalenyl-containing complex. Broad spectral range third-order nonlinear optical studies employing fs pulses and the Z-scan technique reveal an increase in two-photon absorption cross-section on replacing ligated-gold by -nickel and then -ruthenium for a fixed alkynyl ligand. Computational studies undertaken using time-dependent density functional theory have been employed to assign the nature of the key optical transitions and suggest that the significant optical nonlinearities observed for the ruthenium-containing complexes correlate with the low-energy formally Ru ? NO2 band which possesses strong MLCT character, while the more moderate nonlinearities of the gold complexes correlate with a band higher in energy that is primarily ILCT in character.

Isoselenocarbonyl complexes

The salt elimination reactions of [NEt4][Mo(CSe)(CO)2(Tp?)] ([NEt4][2], Tp? = hydrotris(3,5-dimethylpyrazol-1-yl)borate) with a range of metal halide complexes (ClMLn) have been investigated as a possible route to isoselenocarbonyl complexes [Mo(CSeMLn)(CO)2(Tp?)]. Thus the reactions of [NEt4][2] with [RuCl(L)2(eta-C5R5)] provide molybdenum-ruthenium derivatives [Mo{CSeRu(L)2(eta-C5R5)}(CO)2(Tp?)] (L = PPh3, R = H 4, L = CO, R = Me 5), both of which were structurally characterised. The molybdenum-iron derivative [Mo{CSeFe(CO)2(eta-C5H5)}(CO)2(Tp?)] (6) was obtained from [NEt4][2] and [FeCl(CO)2(eta-C5H5)] however its formulation currently rests on spectroscopic and microanalytical data. The reaction of [NEt4][2] with [RuH(NCMe)(CO)2(PPh3)2]PF6 affords the structurally characterised hydrido-isoselenocarbonyl complex [Mo{CSeRuH(CO)2(PPh3)2}(CO)2(Tp?)] (7) with no indication of coupling of the hydride and selenocarbonyl ligand.

A Spectroscopic and Computationally Minimal Approach to the Analysis of Charge-Transfer Processes in Conformationally Fluxional Mixed-Valence and Heterobimetallic Complexes

Class II mixed-valence bimetallic complexes {[Cp?(PP)M]C?C?C?N[M?(PP)?Cp?]}2+ (M, M?=Ru, Fe; PP=dppe, (PPh3)2; Cp?=Cp*, Cp) exist as conformational ensembles in fluid solution, with a population of structures ranging from cis- to trans-like geometries. Each conformer gives rise to its own series of low-energy intervalence charge-transfer (IVCT) and local d?d transitions, which overlap in the NIR region, giving complex band envelopes in the NIR absorption spectrum, which prevent any meaningful attempt at analysis of the band shape. However, DFT and time-dependent (TD)DFT calculations with dispersion-corrected global-hybrid (BLYP35-D3) or local hybrid (lh-SsirPW92-D3) functionals on a small number of optimised structures chosen to sample the ground state potential energy hypersurfaces of each of these complexes has proven sufficient to explain the major features of the electronic spectra. Although modest in terms of computational expense, this approach provides a more accurate description of the underlying molecular electronic structure than would be possible through analysis of the IVCT band by using the static point-charge model of Marcus?Hush theory and derivatives, or TDDFT calculations from a single (global) minimum energy geometry.

Bis(alkynyl), metallacyclopentadiene, and diphenylbutadiyne complexes of ruthenium

Heating diphenylbutadiyne with [Ru(CO)2(PPh3) 3] or [Ru(CO)3(PPh3)2] in toluene under reflux provides respectively the ruthenacyclopentadiene [Ru{kappa2-CR=CPhCPh=CR}(CO)2(PPh3) 2] (R = C?CPh) or the cyclopentadienone complex [Ru{eta4-O=CC4Ph2R2}(CO) 2(PPh3)], the latter via [2 + 2 + 1] alkyne and CO cyclization. The bis(alkynyl) complex cis,cis,trans-[Ru(C?CPh) 2(CO)2(PPh3)2] is not formed in either of these reactions but is the product of the reaction of [RuCl 2(CO)2(PPh3)2] with LiC?CPh or of cis,-mer-[Ru(C?CPh)2(CO)(PPh3)3] with CO. Although the bis(alkynyl) complex does not undergo reductive elimination to provide the diyne complex, thermolysis of cis,cis,trans-[Ru(C?CPh) (HgC?CPh)(CO)2-(PPh3)2] (obtained from [Ru(CO)2(PPh3)3] and [Hg(C?CPh) 2]) provides a noninterconvertible 1:1 mixture of cis,cis,trans-[Ru(C?CPh)2(CO)2(PPh3) 2] and [Ru(eta-PhC?CC?CPh)(CO)2(PPh 3)2].
