Cyclopentadienyl-ruthenium and -osmium chemistry. XXVIII. Reactions and isomerisation of 1,2-bis(methoxycarbonyl)ethenyl complexes: X-ray structure of Ru<(Z)-C(CO2Me)=CH(CO2Me)>-(CO)(PPh3)(eta-C5H5)*0.5EtOH, and Ru-(PPh3)(eta-C5H5)

A reinvestigation of the reaction between C2(CO2Me)2 and RuH(PPh3)(eta-C5H5) and some related complexes is reported.Initial cis addition is followed by conversion into the trans isomer.In the case of the bis-(PPh3) complex, isomerisation is followed by chelation of the ester CO group with concomitant displacement of one PPh3 ligand.The resulting chelate complex reacts with CO or CNBut to give thr (Z)-RuC(CO2Me)=CH(CO2Me) complexes; the (E)-isomer of the carbonyl complex is obtained by addition of C2(CO2Me)2 to RuH(CO)(PPh3)(eta-C5H5).The (1)H and (13)C NMR spectra are not a reliable guide to assignment of the stereochemistry of the vinyl group.Other products isolated from the initial reaction are tha bis-insertion product and the 1/2 PPh3C2(CO2Me)2 adduct.The molecular structures of Ru<(Z)-C(CO2Me)=CH(CO2Me)>(CO)(PPh3)*0.5EtOH, Ru<(E)-C(CO2Me)=CH(CO2Me)>(dppe)(eta-C5H5) and have been determined.The cis isomer is monoclinic, space group P21, with a 9.328(8), b 17.385(10), c 10.356(7) Angstroem, beta 101.78(3) deg and Z=2; 2107 data with I>/=2.5?(I) were refined to R=0.076, Rw=0.085.The trans isomer is triclinic, space group P1- with a 10.404(7), b 11.221(6), c 13.230(9) Angstroem, alpha 92.67(5), beta 110.56(5), gamma 106.21(5) deg and Z=2; 2520 data with I>/=2.5?(I) were refined to R=0.055, Rw=0.068.The butadienyl complex is monoclinic, space group P21/a, with a 19.655(8), b 8.674(4), c 21.060(5) Angstroem, beta 116.22(3) deg and Z=4; 2724 data with I>/=2.5?(I) were refined to R=0.043, Rw=0.047.

Ruthenium allenylidene and allylcarbene complexes from 1,6-diyne

Reactions of the four 1,6-diynes 1-3 and 7, each with one terminal propargylic alcohol and one internal triple bond containing Me3Si groups, with [Ru]-Cl ([Ru] = Cp(PPh3)2Ru) led to two types of products. In the first type, only the propargylic group is involved in the reaction leading to vinylidene, allenylidene, or acetylide complexes. A C-C bond formation of two triple bonds in 1,6-diynes gave allylcarbene products of the second type. The reaction of 1 with [Ru]-Cl yielded only the first type, giving a mixture of two cationic complexes; the allenylidene complex 8 and the phosphonium acetylide complex 9, the latter resulting from further addition of a phosphine molecule to Cgamma of 8. The same reaction in the presence of excess phosphine gave 9 only. However, with an additional methyl group, the 1,6-diyne 2 reacted with [Ru]-Cl to give the allylcarbene complex 11 also with a phosphonium group on the ligand. The reaction proceeds by a cyclization reaction involving two triple bonds on the metal accompanied by a migration of a phosphine ligand to Calpha. In both reactions strong affinity between alkyne and phosphine was observed, resulting in formations of P-C bonds with different regioselectivity. Addition of HCl to 11 transforms the five-electron-donor allylcarbene ligand to the four-electron-donor diene ligand along with formation of a Ru-Cl bond, giving complex 12 in high yield. From the reaction of [Ru]-Cl with diyne 3 containing a tert-butyl group at the propargylic carbon, both the allenylidene complex 13 and the allylcarbene complex 14 were obtained. The reaction of diyne 7 with [Ru]-Cl also gave both types of complexes, namely the vinylidene complex 16 and the allylcarbene complex 17. Crystal structures of complexes 9, 11, 12, and 16 have been determined by single-crystal X-ray diffraction analysis.

Syntheses, structures, some reactions, and electrochemical oxidation of ferrocenylethynyl complexes of iron, ruthenium, and osmium

The syntheses and characterizations of several complexes containing ferrocenylethynyl and ferrocene-1,1?-bis(ethynyl) groups attached to M(PP)Cp? [M = Fe, Ru, PP = dppe, Cp? = Cp*; M = Ru, Os, PP = (PPh3)2, dppe, Cp? = Cp] are described. Reactions with tetracyanoethene have given either tetracyanobuta-1,3-dienyl or eta3-allylic derivatives, while addition of Me+ afforded the corresponding vinylidene derivatives. Some electrochemical measurements are discussed in terms of electronic communication between the redox-active M(PP)-Cp? groups through the ferrocene nucleus. The molecular structures of 14 of these complexes have been determined by crystallographic methods.

Anticancer activity of structurally related ruthenium(II) cyclopentadienyl complexes

A set of structurally related Ru(eta5-C5H 5) complexes with bidentate N,N?-heteroaromatic ligands have been evaluated as prospective metallodrugs, with focus on exploring the uptake and cell death mechanisms and potential cellular targets. We have extended these studies to examine the potential of these complexes to target cancer cell metabolism, the energetic-related phenotype of cancer cells. The observations that these complexes can enter cells, probably facilitated by binding to plasma transferrin, and can be retained preferentially at the membranes prompted us to explore possible membrane targets involved in cancer cell metabolism. Most malignant tumors present the Warburg effect, which consists in increasing glycolytic rates with production of lactate, even in the presence of oxygen. The reliance of glycolytic cancer cells on trans-plasma-membrane electron transport (TPMET) systems for their continued survival raises the question of their appropriateness as a target for anticancer drug development strategies. Considering the interesting findings that some anticancer drugs in clinical use are cytotoxic even without entering cells and can inhibit TPMET activity, we investigated whether redox enzyme modulation could be a potential mechanism of action of antitumor ruthenium complexes. The results from this study indicated that ruthenium complexes can inhibit lactate production and TPMET activity in a way dependent on the cancer cell aggressiveness and the concentration of the complex. Combination approaches that target cell metabolism (glycolytic inhibitors) as well as proliferation are needed to successfully cure cancer. This study supports the potential use of some of these ruthenium complexes as adjuvants of glycolytic inhibitors in the treatment of aggressive cancers.

1 ,1 -Bis(ethynyl)biferrocene as a linking group for gold, ruthenium, and osmium fragments: synthesis, solid state structures, and electrochemical, UV-Vis, and EPR spectroscopical studies

A series of organometallic mono- and disubstituted bis(alkynyl)biferrocenes of type (LnMC?C)-(HC?C)bfc (LnM = (eta5-C5H5)(Ph3P)2RU (8a), (eta5-C5H5)(Ph3P) 2Os (8b), (eta5 -C5H5)(dppf)Ru (8c); bfc = 1,1 -biferrocenyl, ((eta5 -C5H 4)2Fe)2; dppf = 1,1 -bis(diphenyl)phosphanyl ferrocene, (eta5 -C5H4PPh2) 2Fe) and (LnMC?C)2bfc (LnM = (Ph3P)Au (6), (eta5 -C5H5)(Ph 3P)2Ru (9a), (eta5 -C5H 5)(Ph3P)2Os (9b), (eta5 -C 5H5)(dppf)Ru (9c)) have been synthesized from (HC?C)2bfc (4) with either (Ph3P)AuCl (5) in the presence of HNEt2/[CuI] (synthesis of 6) or LnMX (L nMX = (eta5 -C5H5)(Ph 3P)2RuCl (7a); (eta5 -C5H 5)(Ph3P)2OsBr (7b); (eta5 -C 5H5)(dppf)RuCl (7c)) together with [H4N]PF 6 and KOtBu (synthesis of 8 and 9), respectively. The structures of 6, 8b, 9a, 9b, and 9c in the solid state were determined by single-crystal X-ray structure analysis, showing unsymmetrical (8) or symmetrical geometries (6, 9), with almost eclipsed conformations or approximately midway positions between the fully eclipsed and the fully staggered conformation of the bfc cyclopentadienyl rings and with anti geometry of the linear ethynyl connecting units. UV-vis and NIR spectroscopic measurements suggest a weak interaction between the appropriate metal atoms. The associated radical cations were in situ generated by stepwise chemical oxidation and characterized by continuous wave electron paramagnetic resonance (EPR) investigations in X-band performed at low temperature.
