By reaction of the hydrazones of mono-and 1,1?-diacetylferrocene with mono-and diketones a series of ferrocenylazines has been prepared. The crystal structures of the monobridged ferrocenophane [4](1)(1,4-dimethyl-2,3-diazabuta-1,3-dien) ferrocenophane (II) and of the dibridged ferrocenophane [42](1,1?)bis-(1,4-dimethyl-2,3-diazabuta-1,3-dien) ferrocenophane (VII) have been determined. II exists as a centrosymmetric molecule with eclipsed cyclopentadienyl rings and a planar MeC=NN=CMe bridge whereas VII has staggered cyclopentadienyl rings and non-planar bridges. In II and VII the bridges are in the E,E configuration. The electrochemical results show that the ferrocenium ions of the acetylferrocene and the azines are stable in solution whereas those of the hydrazones are unstable. In agreement with a slightly increasing electronic communication between the two ferrocene units, II undergoes two almost overlapping one-electron oxidations (DeltaE? = 0.09 V) whereas VII displays two more widely separated one-electron oxidations (DeltaE? = 0.12 V).

In our search for new anticancer drugs, a series of binuclear ruthenium(III) thiosemicarbazone complexes of the type [RuCl 2(EPh3)]2L (where E = P/As; L = binucleating monobasic tridentate thiosemicarbazone ligand) have been synthesized. Structural features were determined by various physico-chemical and spectral techniques. The interactions of these complexes with CT-DNA were investigated by absorption spectral study, indicates that the binuclear ruthenium(III) complexes form adducts with DNA and has intrinsic binding constant in the range of 1.0 × 104-7.9 × 104 M-1. The free radical scavenging activity of binuclear ruthenium(III) complexes have been determined by their interaction with the stable DPPH free radical. All the complexes exhibited significant antiproliferative activity against human breast cancer line, MCF-7. This research may provide knowledge that is an excellent backdrop for the rational design of promising drugs.

The structures adopted by a range of hydrotris(3,5-dimethylpyrazolyl) methane complexes [ML2{HC(pz?)3}]+ (M = Rh, Ir; L2 = diene) have been investigated. There is low steric hindrance between ligands in [Rh(eta-nbd){HC(pz?)3}] + (nbd = norbornadiene) and [Rh(eta-dmbd){HC(pz?) 3}]+ (dmbd = 2,3-dimethylbuta-1,3-diene) resulting in kappa3 co-ordination of the pyrazolylmethane. The complexes [M(eta-cod){HC(pz?)3}]+ (cod = cycloocta-1,5-diene) (M = Rh, Ir) are kappa2 co-ordinated with the free pyrazolyl ring positioned above and approximately parallel to the square plane about rhodium or iridium. The HC(pz?)3 complexes undergo fast exchange of the co-ordinated and unco-ordinated pyrazolyl rings on the NMR spectroscopic timescale. However, for [Rh(eta-dmbd){HC(pz?) 3}]+, the fluxional process is slowed at low temperatures, so that inequivalent pyrazolyl rings may be observed. A mechanism for the fluxional process is proposed involving dynamic interconversion between isomeric forms in solution. The bonding mode of the HC(pz?)3 ligand can be determined by 13C NMR spectroscopy. The 13C chemical shifts (for the sp3 hybridised carbon of the ligand) show the general pattern, kappa3 < 71.5 ppm < kappa2. The electrochemical behaviour of the pyrazolylmethane complexes is related to the degree of structural change, which occurs on electron transfer and is compared with that of the pyrazolylborate analogues. The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing theoretical assessments of solvent structures and their interactions with reaction intermediates and transition states.

Treatment of [Fc-1-R1-1?-R2] (R1 = H, R2 = CH(O); R1 = H, R2 = CMe(O); R1 = R2 = CMe(O)) with LiC{triple bond, long}CCH2OLi (prepared in situ from HC{triple bond, long}CCH2OH and n-BuLi) affords the ferrocenyl-substituted but-2-yne-1,4-diol compounds of general formula [Fc-1-R1-1?-{CR(OH)C{triple bond, long}CCH2OH}] (R1 = R = H (1a); R1 = H, R = Me (1b); R1 = CMe(O), R = Me (1c)) in low to high yields, respectively (where Fc = Fe(eta5-C5H4)2). In the case of the reactions of [Fc-1-R1-1?-R2] (R1 = H, R2 = CH(O); R1 = R2 = CMe(O)), the by-products [Fc-1-R1-1?-{CR(OH)(CH2)3CH3}] (R1 = R = H (2a); R1 = CMe(O), R = Me (2c)) along with minor quantities of [Fc-1,1?-{CMe(OH)(CH2)3CH3}2] (3) are also isolated; a hydrazide derivative of dehydrated 2c, [1-(CMe{double bond, long}CHCH2CH2CH3)-1?-(CMe{double bond, long}NNH-2,4-(NO2)2C6H3)] (2c?), has been crystallographically characterised. Interaction of 1 with Co2(CO)8 smoothly generates the alkyne-bridged complexes [Fc-1-R1-1?-{Co2(CO)6-mu-eta2-CR(OH)C{triple bond, long}CCH2OH}] (R1 = R = H (4a); R1 = H, R = Me(4b); R1 = CMe(O), R = Me (4c)) in good yield. Reaction of 4a with PhSH, in the presence of catalytic quantities of HBF4 · OEt2, gives the mono- [Fc-1-H-1?-{Co2(CO)6-mu-eta2-CH(SPh)C{triple bond, long}CCH2OH}] (5) and bis-substituted [Fc-1-H-1?-{Co2(CO)6-mu-eta2-CH(SPh)C{triple bond, long}CCH2SPh}] (6) straight chain species, while with HS(CH2)nSH (n = 2,3) the eight- and nine-membered dithiomacrocylic complexes [Fc-1-H-1?-{cyclo-Co2(CO)6-mu-eta2-CH(S(CH2)n-)C{triple bond, long}CCH2S-}] [n = 2 (7a), n = 3 (7b)] are afforded. By contrast, during attempted macrocyclic formation using 4b and HSCH2CH2OCH2CH2SH dehydration occurs to give [Fc-1-H-1?-{Co2(CO)6-mu-eta2-C({double bond, long}CH2)C{triple bond, long}CCH2OH}] (8). Single crystal X-ray diffraction studies have been reported on 2c?, 4b, 4c, 7b and 8.

A new range of potentially tetradentate proligands, H2L, derived from aromatic aldehydes and ketones and aliphatic diamines has been prepared. Their vanadyl(IV) and vanadyl(V) complexes [VO(L)] and [VO(L)]+, and also some adducts [VO(L)?VO(L)]+, have been synthesized. The structures of four selected complexes have been determined and it is shown that these must be a result of both steric and electronic factors that make prediction of conformation and stacking difficult. The adducts [VO(L)?VO(L)]+ have structures that persist in solution in dichloromethane, where they can undergo redox chemistry, but they apparently dissociate into their component complexes in the donor solvent acetonitrile.

A series of <3>ferrocenophane(FcP) derivatives have been investigated using 57Fe Moessbauer and 1H NMR spectroscopy.For the 2- and 3-acetyl-FcP in neutral and acidic mrdia, proton resonances were assigned by analogy with the unbridged species, which themselves were analysed using specifically alpha deuteriated compounds. 2-Acetyl-FcP exhibited a strongly shielded methyl group due to out of plane deformation of the carbonyl function.The corresponding carbenium ions were produced from the parent alcohols in CF3CO2 and their NMR spectra discussed. <3>Ferrocenophan-6,8-dione(A) was unprotonated in CF3CO2H, monoprotonated in 80percent H2SO4 to give the symmetrical carbenium ion.The NMR spectrum of the ion is fully discussed.Moessbauer spectra of 2- and 3-acetyl-FcP revealed the latter to have an anomalously low value of both quadrupole splitting (QS) and isomer shift (IS).The QS of frozen solutions of A at pH 13 show little change from those of ferrocene indicating that the carbanionic charge creates a symmetrical electron density about the iron atom by repulsion of the r2g electrons.The carbenium ion generated at the 2 position in <3>FcP showed a higher QS than that in the 3-position due to better overlap with e2g orbitals.The symmetrical carbenium ion derived from dehydro-<3>ferrocenophane showed exalted QS values indicative of iron e2g orbital overlap.The effect of bridging on Moessbauer parameters is also discussed.

In a patent，Which mentioned a new discovery about 1273-94-5

Condensation of 1,1?-diacetyl ferrocene with 2-amino-5-methylthiazole in 1: 2 molar ratio yields a ferrocenyl Schiff base ligand 1,1?-bis(Z)-N-ethyldiene-5-methylthiazol-2-amine ferrocene (L). This ligand forms 1:1 complexes with La(III), Ce(III), Pr(III) and Gd(III) nitrate in a good yield. Characterization of the ligand and complexes were carried out using infrared, nuclear magnetic resonance, mass spectra, electronic absorption, magnetic susceptibility, molar conductivity and elemental analysis. The cytotoxicity and in vitro anticancer evaluation of the ligand and its complexes have been assessed against four different human tumor cell lines (MCF-7, HepG2, A549 and HCT116). The results revealed that the prepared compounds exert their actions in HepG2 and MCF-7 through inhibition of the activity of both urokinase and histone deacetylase (HDAC). Pr-complex revealed promising anticancer activity compared to the activity of the commonly used anticancer drug, doxorubicin.
