, p. 2660 - 2665 (2017/03/06)
A convergent and regioselective synthesis of silicon-bridged 4-arylpyridines has been developed through a rhodium-catalyzed [2+2+2] cycloaddition of silicon-containing diynes with nitriles. The absorption and emission properties of these compounds have be

A series of four asymmetrically aryl-substituted 9,9′-spiro-9- silabifluorene (SSF) derivatives, 2,2′-di-tert-butyl-7,7′-diphenyl- 9,9′-spiro-9-silabifluorene (PhSSF), 2,2′-di-tert-butyl-7,7′- dipyridin-2-yl-9,9′-spiro-9-silabifluorene (PySSF), 2,2′-di-tert- butyl-7,7′-dibiphenyl-4-yl-9,9′-spiro-9-silabifluorene (BPhSSF), and 2,2′-di-tert-butyl-7,7′-bis(2′,2″-bipyridin-6-yl)-9, 9′-spiro-9-silabifluorene (BPySSF) are prepared through the cyclization of the corresponding 2,2′-dilithiobiphenyls with silicon tetrachloride. These novel spiro-linked silacyclopentadienes (siloles) form transparent and stable amorphous films with relatively high glass transition temperatures (Tg = 203-228°C). The absorbance spectrum of each compound shows a significant bathochromic shift relative to that of the corresponding carbon analogue as a result of the effective σ*-π* conjugation between the σ* orbital of the exocyclic Si-C bond and the π* orbital of the oligoarylene fragment. Solid-state films exhibit intense violet-blue emission (λPL = 398-415 nm) with high absolute photoluminescence quantum yields (ΦPL = 30-55%).
Mild and efficient direct aromatic iodination
Johnsson, Richard,Meijer, Andréas,Ellervik, Ulf
, p. 11657 - 11663 (2007/10/03)
Aryl iodides are important synthetic intermediates that can be transformed into tritium labelled compounds by metal-mediated hydrodehalogenation and also react in a number of important synthetic transformations. We present ICl/In(OTf)3 as a new reagent combination for mild iodination, suitable for acid-sensitive substrates such as carbohydrates.
