Metallocenes are an important and well-known class of organometallic compounds, which were first discovered by Kealy and Paulson in 1951.[...]

In this review article chiral titanocenes and their application for the enantioselective hydrogenations of different unsaturated compounds are discussed, with a special emphasis on the kinetics and the practicality of the developed systems. The natur...

This review article describes developments in chiral metallocenes as polymerization catalysts focusing on C2 symmetric ansa-zirconocene complexes. Selective synthesis of rac-isomers of ansa-zirconocenes are surveyed. Isospecific polymerizations of pr...

Some novel β-biarylacryl ferrocene derivatives were synthesized viaPd-catalytic Suzuki cross-coupling reactions of β-(2-bromophenyl)acrylferroceneand arylboronic acids. The structures were determined with elemental analyses, IRspectra, and ¹H-NMR spe...

The synthesis, spectroscopic characterization and X-ray crystal structure of a newchiral triosmium alkylidyne carbonyl cluster, (R,S)-[Os₃(μ-H)₂(CO)₉{μ₃-CPPh₂(η⁵-C₅H₄)Fe(η⁵-C₅H₃(PPh₂)CH(Me)NMe₂)}] (1) are described. Compound 1 crystallizes in thenon-...

Two-step synthesis of 1,1’-di(α-dimethylamino)ethylferrocene is described in details. Cyclopalladation of this diamine involving one or two amino groups is reported and the product of asymmetric mono-cyclopalladation is fully characterized.

The reactions of bis(cyclopentadienyl)titanium(IV)/zirconium(IV) dichloridewith a series of imine-oxime ligands (LH₂), derived by condensing benzil-α-monoxime and2-phenylenediamine, 4-phenylenediamine, 4-methyl-2-phenylenediamine, 2,6-diamino-pyridin...

Activities during ethylene/1-hexene copolymerization were found to increaseusing the mixed titania/silica-supported MAO with rac-Et[Ind]₂ZrCl₂ metallocenecatalyst. Energy Dispersive X-ray spectorcopy (EDX) indicated that the titania wasapparently loc...

Five different silica gels containing two chiral ferrocenyl ligands were prepared by various synthetic routes and tested in an enantioselective Pd(0)-catalyzed allylic substitution and Rh-catalyzed hydrogenation. All the prepared anchored ligands wer...

Ferrocenylnaphthalene diimide 1 can bind to double stranded DNA (dsDNA) by the threading intercalation mode and the resulting complex was stabilized further by β- cyclodextrin (CD) by forming a supramolecular complex. These complex formation processe...

The changes in the electronic absorption spectra (UV-Vis) of some metallocene-doped poly(methyl methacrylate) (PMMA) thin films containing chloroform molecules as impurities were studied after photoexcitation in the nitrogen atmosphere. Photoexcitati...

We report herein the effect of palladium on the redox electrochemistry of ferrocene monocarboxylic acid encapsulated within an organically modified sol-gel glass network (ORMOSIL). It has been found that amount of palladium and its geometrical distri...

Managing a chemical inventory consists of tracking the usage, disposal, and ordering of substances that are at the heart of an enterprise’s endeavors.[...]

Cyclopentadienyl-titanium complexes containing –OC₆H₄X ligands (X = Cl,CH₃) activated with methylaluminoxane (MAO) were used in the homo-polymerizationof ethylene, propylene, 1-butene, 1-pentene, 1-butene, and 1-hexene, and also in co-polymerization...
