[reaction: see text] Nanometer tin-mediated allylation of aldehydes or ketones in distilled or tap water gave rise to corresponding homoallyl alcohol in high yield without any other assistance such as heat or supersonic or acidic media.

X-ray diffraction studies reveal the structure of {[(2-C(6)H(5)-1,2-C(2)B(10)H(10)-1-COO)Bu(2)Sn](2)O}(2), 1, to conform to the common motif found for {[(R'COO)R(2)Sn](2)O}(2) compounds. The dimer features a central Bu(2)Sn(2)O(2) unit (two-fold symmetry) with the two Bu(2)Sn groups being linked via bridging oxygen atoms, each of which also carries an exocyclic Bu(2)Sn moiety. The two pairs of ...

Tin(IV) and organotin(IV) compounds, a deceptively simple area of inorganic and metal-organic chemistry, have been receiving more attention due to the important industrial (Tammy and Georges, 2005) and environmental applications. Nitrogen, oxygen, and sulfur donor ligands have been used to enhance the biological activity of organotin derivatives (Mohammad et al., 2004; Jason et al., 2000). Also...

The objective of the present work was to investigate the effect of selected organic tin compounds and potassium chloride (used as a reference substance) on the trans-membrane electric voltage and electric resistance of model membranes, the latter being nitrocellulose filters impregnated with butylene ester of lauric acid. The increasing KCl concentration (in the measurement chambers) caused a r...

A series of compounds based on the angular-shaped naphthalene tetracarboxylic diimide core have been synthesized, characterized and used as active layers of organic field-effect transistors (OFETs). The fabricated OFET devices exhibit n-type semiconducting characteristics, demonstrating the first examples of semiconductors based on angular-shaped naphthalene tetracarboxylic diimides.

ABSTRACTA novel floatation-spectrophotometric extraction method was developed for the recovery of tin (II) from aqueous samples prior to determination by UV spectrophotometric detection. The method is based on the formation of a complex between tin (II) and kalmagyte in pH=8. The complex is floated in the interface of n-hexane and aqueous phases. After removing the aqueous phase, the floated pa...

We report the optoelectronic properties occurring in single-walled carbon nanotubes ~SWNTs!— conjugated polymer, poly~3-octylthiophene! composites. Composite films were drop or spin cast from a solution on indium–tin oxide ~ITO! and quartz substrates and studied using absorption spectroscopy and electrical characterization methods. Diodes ~Al/polymer-nanotube composite/ ITO! with a low nanotube...

Tributyltin (TBT) and other organotin compounds have been restricted for use on leisure boats since 1989 in the EU. Nonetheless, release of TBT is observed from leisure boats during hull maintenance work, such as pressure hosing. In this work, we used a handheld X-ray Fluorescence analyser (XRF) calibrated for antifouling paint matrixes to measure tin, copper and zinc in antifouling paints coat...

Key assets for transparent electric contacts in optoelectronic applications are high conductivity and large transparency over extended spectral range. Indium-Tin-Oxide Aluminium-doped-Zinc-oxide commercial examples, with their electrical resembling those of metals, despite, being limited up to 1.5µm. This work introduces smooth compact amorphous thin films n -type semiconducting WO 3-x prepared...
