This update reviews the major developments on rotaxane-based shuttles during the period of August 2008 to October 2010 and is organized similarly to the previous review [1]. The progress in the field of chemical controlled shuttles can be summarized as a significant increase of the shuttling rates, second-generation pH-switchable Pd(II)-complexed rotaxanes, and new synthetic approaches, especially those based on Read More

This review reports on the synthesis of 7-deazapurine (pyrrolo[2,3-d]pyrimidine) 2'-deoxyribonucleosides, including β-D- and β-L-enantiomers, fluoro derivatives, and 2',3'-dideoxyribonucleosides. It covers the various aspects of convergent nucleoside synthesis. Stereochemically defined α-D and α-L 2'-deoxyribonucleosides as well as sugar derivatives were prepared by nucleobase anion glycosylation. This glycosylation reacti Read More

Carbenoids are transient species whose reactivity resembles that of free carbenes. They can be generated by several procedures, for instance, by the interaction of diazo compounds with transition metals, such as copper, ruthenium and rhodium complexes. They are able to react with various unreactive substrates, and their use has become very popular among synthetic organic chemists. The carbenoid transfer reactions are Read More

This review is focused on current state of materials design and syntheses of organic semiconductors for thin-film field effect transistors (FETs). Recently, high performance p- or n-type organic FETs with high charge carrier mobility, high ON-OFF current ratios and high stability have been achieved due to the improvement of materials synthesis. Intrinsic electronic properties, solid-state packing, stability, and the capability o Read More

Many effective strategies have been developed in order to inhibit the hydrodehalogenation in the selective hydrogenation of halonitrobenzene to haloaniline. However, hydrogenolysis of the carbon-halogen bond of the produced haloaniline as a defect of the hydrogenation process could not be avoided completely over usual metal catalysts, especially at complete conversion of the substrates. In the past few years, we reporte Read More
