The solvent effect on the position of the carbonyl vibrational stretching of acetylferrocene in aprotic media was studied in this work. The solvent-induced shifts in this organometallic compound were interpreted in terms of the alternative reaction field model(SCRF-MO) proposed by Kolling. In contrast to the established trends for carbonyl groups in organic systems, the results suggest that the...

A new family of organometallic compounds, organozirconium reagents, are shown to serve as suitable partners in cross-coupling reactions of (activated) secondary alkyl electrophiles. Thus, the first catalytic method for coupling secondary alpha-bromoketones with alkenylmetal reagents has been developed, specifically, a mild, versatile, and stereoconvergent carbon-carbon bond-forming process that...

Esterification of (4-hydroxyphenyl)diphenylphosphine, coordinated to the [Ru(η6-p-cymene)Cl2] fragment, allows a series of bioactive carboxylic acids to be introduced directly into the organometallic molecule. Evaluation of the compounds on human ovarian cancer cells reveals synergistic enhancements in their antiproliferative activity relative to their bioactive organic and organometallic precu...

Historically, platinum has played a prominent role in organometallic chemistry. The compounds KPtCI,(C,H,)H,O (I), PtMe, (X) (2) and Chugaev's salt [PtC,H,,N,],Clx (3, 4) present some of the fist examples of stable metal-olefin, metal-alkyl and metalcarbene complexes, although ironically the nature of the bonding in these compounds was not immediately recognised. In the study of organometallic ...

A method based on the determination of maximum common substructures is applied for the generation of substructures which are characteristic for a given set of molecular structures. The molecular structures are from hitlists obtained by spectral library searches; the hitlists contain those reference compounds, which have infrared spectra most similar to that from the query compound. The influenc...

Goals and Scope The ICEBAMO meetings aim to facilitate interdisciplinary discussion on environmental and biological aspects of main-group organometals. have brought together researchers from the fields of toxicology, environmental sciences, analytical chemistry, biochemistry, and synthetic organometallic chemistry. ICEBAMO 2001 at the castle of Schieileiten, which is located about 50 km east of...
