Heterogeneous catalysts have been synthesi zed by the conjugation of Hoveyda-Grubbs second-generation catalyst with a lipase. The catalytic properties of the organometallic compound in solution were firstly optimized, evaluating the activity of Ru in the ring-closing metathesis of diethyldiallymalonate at 25 °C at different solvents and in the presence of different additives. The best result wa...

A chemistry-based approach to designing precursors for the deposition of inorganic films requires consideration of the physical properties of the precursor compound (e.g., volatility for transport in the reactor) and its probable decomposition pathways, both in the gas phase and on the surface during growth. We have been using Aerosol-Assisted Chemical Vapor Deposition of tungsten carbonitride ...

The results of comparison of experimental C1 NQR parameters for a great number of organic and organometallic compounds and estimated ones using ab initio calculations at the RHF/6-31G(d) level were systematized. The NQR frequency changes on going from one compound to another depend, in general, on the changes of populations of the CI atom p„-orbitals in these compounds and, first of all, of pop...

The title compound, [Fe(C(5)H(5))(C(7)H(5)Cl(2))], represents a versatile building block for the preparation of π-conjugated redox-active compounds or polymetallic organometallic systems due to the presence of the electrochemically active ferrocenyl unit. It is therefore a potential starting material for the preperation of the corresponding alkyne. In the crystal, the alkenyl unit and the cyclo...

Thermodynamic data such as the binding constants are vital parameters describing interactions between exotic trace compounds and biomolecules in biochemical property modeling. In this study, the stability constants of organometallic compound and protein complexes were studied by using capillary electrophoresis coupled with inductively coupled plasma mass spectrometry (CE-ICP-MS), considering it...

Synthetic chemicals are extremely important in all fields of our life and their cheap production in large amounts is necessary for the successful economic growth of modern civilization. Catalysis offers the unique possibility of fast and selective synthesis of desired chemical molecules without consumption of extra amounts of energy and theoretically without the consumption of catalyst itself. ...

The influence of precursor structure and reactivity on properties of compound semiconductors grown by metalorganic chemical vapor deposition (MOCVD) is discussed and illustrated with examples for growth of GaAs, ZnSe, and A1,Gal-,N. Gas-phase and surface reactions of organometallic arsenic compounds provide understanding of variation in carbon incorporation levels with precursor structure. Surf...

Ferrocenyl diphenol tamoxifen derivative (Fc-diOH) is one of the most active molecules of a new class of organometallic drugs, showing in vitro antiproliferative effects on both hormone-dependent and independent breast cancer cells. For the first time, Fc-diOH was tested on a 9L glioma model according to two encapsulation strategies: lipid nanocapsules (LNC) and swollen micelles. LNC showed a h...

A chiral second-generation organoruthenium half-sandwich compound is disclosed that shows a remarkable selectivity and cellular potency for the inhibition of glycogen synthase kinase 3 (GSK-3). The selectivity was evaluated against a panel of 57 protein kinases, in which no other kinase was inhibited to the same extent, with a selectivity window of at least tenfold to more than 1000-fold at 100...
