TL;DR: A series of group 14 metalloles, from silole to stannole, together with cyclopentadiene, having two thienyl groups at the 2,5 positions, have been prepared.
TL;DR: In this article, the first isolable electronically unsymmetrical silylene, dineopentylpyrido[b]-1,3,2λ2-diazasilol, and the analogous germylene and stannylene (right) are presented and characterized by NMR and photoelectron spectroscopy.
Abstract: The first isolable electronically unsymmetrical silylene, dineopentylpyrido[b]-1,3,2λ2-diazasilol, and the analogous germylene and stannylene (right) are presented and characterized by NMR and photoelectron spectroscopy. In contrast to nonisolable analogous pyrido[c] derivatives, the pyrido[b] derivatives possess a symmetrical π charge density distribution in the HOMO from a nodal plane through the pyrido nitrogen atom.
TL;DR: The synthesis, structures, and physical and chemical properties of mono-and dianions of group 14 metalloles (1-metallacyclopentadiene), heavier congeners of the cyclopentadienyl anion, are described in this article.
TL;DR: The first tin-analog of the cyclopentadienyl anion, dilithiostannoles, were successfully synthesized by reduction of the corresponding 1,1-diphenyl derivatives.
TL;DR: In this paper, the synthesis of silyl-substituted dilithiostannoles, which were characterized by NMR spectroscopy and X-ray diffraction analysis, was reported.
