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...
