The synthesis of two new donor-acceptor ferrocenyl derivatives with Meldrum’s acid based nonplanar acceptor substituents is presented. Both compounds are obtained in high yields in a simple reaction protocol under mild conditions using either 1-acetyl- or 1,1?-diacetylferrocene and Meldrum’s acid. Both products have been characterized spectroscopically, by single-crystal X-ray structure analysis, by electrochemical and UV/vis/IR spectroelectrochemical measurements, and by (TD)-DFT calculations. The spectroelectrochemical measurements disclose that the 2,2-dimethyl-1,3-dioxane-4,6-dione moiety is a moderately strong electron acceptor. (Figure Presented)

The ruthenium(II) ferrocenyl heterocyclic thiosemicarbazone complexes of the type [RuCl(CO)(EPh3)]2L (where E = P/As; L = binucleating monobasic tridendate thiosemicarbazone ligand) have been investigated. Strutural features were determined by analytical and spectral techniques. Binding of these complexes with CTDNA by absorption spectral study indicates that the ruthenium(II) complexes form adducts with DNA and has intrinsic binding constant in the range of 3.3 × 104 – 1.2 × 105 M?1. The complexes exhibit a remarkable DNA cleavage activity with CT-DNA in the presence of hydrogen oxide and the cleavage activity depends on dosage.

A series of ferrocene-containing mono- and bis-dihydropyrimidines (DHP’s) were prepared by boric acid mediated three-component Biginelli reactions of formyl- and 1,1?-diformylferrocene, 1,3-dioxo-components and urea. A few further transformations including hydrogenolysis of a benzyl 4-ferrocenyl-DHP-5-carboxylate were also performed. Novel cis-fused saturated pyrimido[4,5-d]pyrimidine-2,7(1H,3H)-diones incorporating [3]-ferrocenophane moiety were constructed by means of iron(III)-catalyzed Biginelli-like condensations of 1,1?-diformylferrocene with urea and in situ generated methyl ketone-derived silyl enol ethers. The structures of the new compounds were established by IR and NMR spectroscopy, including HMQC, HMBC and DEPT measurements.

A series of semi-aromatic diamine monomers (1,m-bis (4-amino benzoyloxy) alkanes; m = 2-6) having in-built ester linkages with variable methylene spacers were synthesized in two steps from aliphatic diols and p-nitrobenzoyl chloride and characterized by their melting points, elemental analysis, FTIR, 1H and 13C NMR spectroscopic studies. The diamines were then polymerized in-situ with ferrocene-based organometallic and terephthaloyl- as well as isophthaloyl-based organic acyl chlorides along with telechelic polydimethylsiloxane oligomer to produce a novel set of ferrocene-containing siloxane-based block copolymers and their organic analogues. The corresponding polyesteramides of the synthesized copolymers, without siloxane segment, were also prepared for comparative studies. The structural features of the organometallic and organic block copolymers along with their respective polyesteramides were confirmed by their physical properties and spectroscopic studies. The molecular parameters of all these materials were determined by static laser light scattering (LLS) technique and glass transition temperatures (Tg) were obtained by differential scanning calorimetry (DSC). The materials were soluble in sulphuric acid and partially soluble in common organic solvents at room temperature, yet become readily soluble upon N-trifluoroacetylation. The morphological information of the synthesized materials was obtained by X-ray diffraction and surface studies (SEM and AFM).

In heterogeneous catalysis, catalysts provide a surface to which reactants bind in a process of adsorption. In homogeneous catalysis, catalysts are in the same phase as the reactants. Formula: C14H6FeO2. Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. Introducing a new discovery about 1273-94-5, Name is 1,1′-Diacetylferrocene

The complex [Rh(CO)2{HC(pz?)3}][PF6], 1 +[PF6]- {HC(pz?)3 = tris(3,5-dimethylpyrazolyl)methane}, prepared by reacting [{Rh(CO)2(mu-Cl)}2] with HC(pz?)3 in the presence of Tl[PF6], has a distorted square pyramidal structure with a kappa3-HC(pz?)3 ligand. Carbonyl substitution with Lewis bases gives [Rh(CO)L{HC(pz?)3}] [PF6] {L = PPh3, 2+[PF6]-; L = AsPh3, 3+[PF6]-; L = P(o-tolyl)3, 4+[PF6]-}, which have square planar kappa2 structures, confirmed by X-ray crystallography for 2+[PF6]-. The cations 2+ and 3+ have the third pyrazolyl ring orientated pseudo-parallel to the square planar metal whereas 4+ more likely has the third ring orientated exo to that plane. One-electron oxidation of 2+ and 3+ gives the Rh(II) dications [Rh(CO)(PPh3){HC(pz?)3}]2+, 22+, and [Rh(CO)(AsPh3){HC(pz?)3}]2+, 32+, characterised by ESR spectroscopy. Complex 1+[PF6]- reacts with PhC?CPh to give [Rh(CO)(eta2-PhC?CPh)-{HC(pz?)3}] [PF6], 5+[PF6]-, in which the two-electron donor alkyne occupies an equatorial position in a trigonal bipyramidal kappa3 structure. With MeC?CR (R = Me or Et), 1+[PF6]- gives the kappa2 square planar complexes [Rh{eta4-C4Me2R2C(O)}{HC(pz? )3}][PF6] (R = Me, 6+[PF6]-; R = Et, 7+[PF6]-) in which the cyclopentadienone ligands are coordinated via two Rh-monoalkene bonds; the structurally characterised form of 7+ has the two alkyne units linked head-to-head with the CEt termini bound to the ketonic CO group. With HC?CPh or HC?CH, 1+ gives the octahedral, kappa3 rhodium(III) metallacyclopentadienes [Rh(CO)(eta1:eta1?-CHCRCHCR) {HC(pz?)3}][PF6] (R = Ph, 8+[PF6]-; R = H, 9+[PF6]-) with the two alkynes linked head-to-tail in 8+. The reaction of 1+ with HC?CH also gives the cycloheptatrienone (tropone) derivative [Rh{eta4-C6H6C(O)}{HC(pz?)3} ][PF6], 10+[PF6]-, with a kappa3 ligand and the cycloheptatrienone ligand bound to the metal via two Rh-C sigma-bonds and one Rh-monoalkene interaction.
