The role of organometallic intermediates during on-surface polymerization via Ullmann coupling was studied on Ag(111). The polymerization progress was monitored by X-ray photoelectron spectroscopy (XPS). Scanning Tunneling Microscopy (STM) was used to characterize organometallic and covalent networks and to identify the temperature regimes for organometallic and covalent bond formation.

Until recently, organometallic derivatives were generally viewed as moisture- and air-sensitive compounds, and consequently very challenging to synthesise and very demanding in terms of laboratory requirements (Schlenk techniques, dried solvent, glove box). However, an increasing number of stable, water-soluble organometallic compounds are now available, and organometallic chemistry in aqueous ...

Despite the potential synthetic utility of the reaction, the elements that control the regioand stereochemistry of t he addition of a n organometallic reagent to an olefin have not received careful attention. Our recent studies on the selectivities in organometallic addition to cyclopropenone acetals have revealed some principles of regioand stereocontrol in organometallic additions to olefins....

Organometallic compounds are widely used in almost all sectors of industry. as a result of emissions from natural and anthropogenic sources they are released to the environment, where they undergo a variety of conversions and interactions. some organometallic compounds exhibit high toxicity. organometallic compounds of mercury, tin, lead, selenium and arsenic are among the most common and hazar...

The ICEBAMO meetings aim to facilitate interdisciplinary discussion on environmental and biological aspects of main-group organometals. Previous meetings in Padua (1986 and 1991) and Bordeaux (1994) have brought together researchers from the fields of toxicology, environmental sciences, analytical chemistry, biochemistry, and synthetic organometallic chemistry. ICEBAMO 98 in Odense will provide...

Nucleophilic trapping of iminium salts generated via oxidative functionalisation of tertiary amines is well established with stabilised carbon nucleophiles. The few reports of organometallic additions have limited scope of substrate and organometallic nucleophile. We report a novel, one-pot methodology that functionalises N-substituted tetrahydroisoquinolines by visible light-assisted photooxid...

Organometallic polymer research offers many potential academic and industrial rewards because of the number of elemental variations possible. Unfortunately, there are no general synthetic methods as found for carbon based polymers. Transition metal catalysed dehydrocoupling reactions may prove to be generally applicable to the synthesis of silicon based organometallic polymers. We report here o...

Following the pioneering Ziegler addition of nucleophiles to nonactivated unsaturated carbon–carbon bonds, the controlled carbometallation reaction has emerged. Since then, reactions that result in the addition of a carbon–metal bond of an organometallic across a carbon–carbon unsaturated system, leading to a new organometallic in which the newly formed carbon–metal bond can be used for further...

In the recent years, organometallic compounds have become recognized as promising anti-cancer drug candidates. While radioactive (186/188)Re compounds are already used in clinics for cancer treatment, cold Re organometallic compounds have mostly been explored as luminescent probes for cell imaging and photosensitizers in photocatalysis. However, a growing number of studies have recently reveale...
