In recent years, internally Sn–N coordinated organotin hydrides have found an application in organic syntheses, which involve radical chain reactions. Unique reactivity of such hydrides suggests the potential of intramolecular coordination for the control of radical reactions. When the tin hydrides are used in the presence of Lewis acids single-enatiomer outcomes are accessible. This opens a ne...

A novel electrospray ionization (ESI) mass spectrometric approach for the structure elucidation of ionic organotin(IV) compounds or complexes with weakly bonded ligands as for example monodentate carboxylates or sulfonates is proposed using both positive-ion and negative-ion ESI tandem mass spectra. The ionization mechanism of organotin(IV) compounds involves the cleavage of the most labile bon...

The temporal and spatial distributions of organic tin compounds, irgarol and metals in sediments from a marina and the harbor of a small town near Stockholm, Sweden were investigated as part of a study of the environmental impacts of anti-fouling paint. The upper (0-2 cm) sediment layer was collected at seven stations in the marina and eight stations in the small town harbor; two reference stat...

CH functionalization is a convenient methodology with broad application in total synthesis and medicinal chemistry that provides the same products as already well established cross-coupling methodologies, but with the advantage of avoiding the use of metallic species such as Grignard, boron, silicon and tin compounds. Herein, we report an unprecedented palladium-catalyzed intramolecular direct ...

We present a detailed theoretical study of three alkaline earth compounds Ca2Pb, Sr2Pb and Ba2Pb, which have undergone little previous study, calculating electronic band structures and Boltzmann transport and bulk moduli using density functional theory. We also study the corresponding tin compounds Ca2Sn, Sr2Sn and Ba2Sn. We find that these are all narrow band gap semiconductors with an electro...

Self-assembled nanoporous tin-based hybrid thin films prepared by the sol-gel method from organically-bridged ditin hexaalkynides detect hydrogen gas from 50 to 200 °C at the 200-10,000 ppm level. This finding opens a fully new class of gas-sensing materials as well as a new opportunity to integrate organic functionality in gas sensing metal oxides.

Transparent electronics has attracted numerous research efforts in recent years because of its promising commercial impact in a wide variety of areas such as transparent displays. High optical transparency as well as good electrical performance is required for transparent electronics. Preseparated, semiconducting enriched carbon nanotubes are excellent candidates for this purpose due to their e...

Reduction of an N-heterocyclic carbene (NHC) adduct of SnCl(2), viz. [(IPr)SnCl(2)] (IPr = :C{N(Dip)C(H)}(2); Dip = 2,6-diisopropylphenyl), with a magnesium(I) dimer, has afforded the first NHC complex of a row 5 element in its diatomic form, [(IPr)Sn=Sn(IPr)]; a computational analysis of the complex indicates that it comprises a singlet state, doubly bonded tin(0) fragment, :Sn=Sn:, datively b...

Semiconducting polymers have previously been used as the transduction material in X-ray dosimeters, but these devices have a rather low detection sensitivity because of the low X-ray attenuation efficiency of the organic active layer. Here, we demonstrate a way to overcome this limitation through the introduction of high density nanoparticles having a high atomic number (Z) to increase the X-ra...
