Publikováno v: CHIMIA, Vol 57, Iss 3 (2003)
Chemistry teaching is traditionally a difficult task as it comes alive only through experiments. Secondly, extreme reductionism does not apply to chemical understanding because chemical ensembles by definition constitute very large sets of mobile par

Tailor-made synthesis of functional substituted oligo- and polysilanes from silyl triflates and (aminosilyl)lithium compounds
Autor: Wolfram Uhlig
Publikováno v: Journal of Organometallic Chemistry. 685:70-78
Diethylamino substituted silyllithium compounds have been prepared in situ from the corresponding phenylchlorosilanes and lithium. These reagents undergo coupling reactions with triflate derivatives of silanes and oligosilanes. Exchange processes ana

Synthesis, functionalization, and cross-linking reactions of organosilicon polymers using silyl triflate intermediates
Autor: Wolfram Uhlig
Publikováno v: Progress in Polymer Science. 27:255-305
The design and synthesis of new materials are two key steps in the advancement of technology. One of the most promising approaches of development of new materials that combine advantages of organic polymers with those of inorganic solids is to devise

Autor: Wolfram Uhlig
Publikováno v: Silicon Chemistry. 1:129-137
New synthetic routes to organosilicon polymers containing SiH2 groups and organic π-electron units in the polymer main chain are described. These polymers are expected to be useful precursors for ceramics. The polymer backbone is formed by condensat

Synthesis, functionalization and crosslinking reactions of poly[(silylene)-1,4-phenylenes] and poly[(silylene)-2,5-thienylenes] using silyl triflate intermediates
Autor: Wolfram Uhlig
Publikováno v: Polymers for Advanced Technologies. 12:607-615
Treatment of silylbis(triflates), RMeSi(OTf)2 (R = p-anisyl, allyl, NMe2) with 1,4-bis(bromomagnesium)­benzene and 2,5-dilithiothiophene, respectively, give poly[(silylene)-1,4-phenylenes] and poly[(silylene)-2,5-thienylenes] in high yields. The RSi

Synthesis and functionalization of Poly[5,5′-(silylene)-2,2′-dithienylene]s using silyl triflate intermediates†
Autor: Wolfram Uhlig
Publikováno v: Applied Organometallic Chemistry. 13:871-879
Treatment of 5,5'-dilithio-2,2'-dithiophene with (dimethylamino)methylsily bis(triflate)- or α, ω-bis(triflate)-substituted trisilanes gave poly[5,5'-(silylene)-2,2'-dithienylene]s in high yields. The amino-silyl bond was cleaved selectively by tri
