Journal ArticleDOI
A stable compound containing a silicon-silicon triple bond.
TL;DR: The reaction of 2,2,3,3-tetrabromo-1,1,4, 4,4-tetrakis[bis(trimethylsilyl)methyl]-1, 4-diisopropyltetrasilane with four equivalents of potassium graphite (KC8) in tetrahydrofuran produces 1,1-4,4-, which shows half the magnitude of the bond shortening of alkynes compared with that
Journal ArticleDOI
Reactivity of a Disilyne RSi≡SiR (R = SiiPr[CH(SiMe3)2]2) toward π-Bonds: Stereospecific Addition and a New Route to an Isolable 1,2-Disilabenzene
TL;DR: In this article, it was shown that the reaction proceeds via the interaction between the LUMO (πin*) of 1 and the HOMO of 2-butene, resulting in a formal [1 + 2] cycloaddition to give the silacyclopropyl−silylene intermediate, followed by its ring expansion to produce the final product.
Journal ArticleDOI
A free cyclotrigermenium cation with a 2π-electron system
TL;DR: The reaction of tetrakis(tri-tert-butylsilyl)cyclotrigermene with trityl tetraphenylborate in benzene produces tris( tri-terT- butylsallyl) cyclotrigermenium tetrapanelborate, which can be isolated as a yellow solid that is stable in the absence of air.
Journal ArticleDOI
Isolable Silyl and Germyl Radicals Lacking Conjugation with π-Bonds: Synthesis, Characterization, and Reactivity
TL;DR: The ESR spectra of 1 and 2 showed strong signals with characteristic satellites due to the coupling with the 29Si and 73Ge nuclei, and small values of the hyperfine coupling constants a(29Si) and a(73Ge) clearly indicate the pi-character of both radicals, corresponding to a planar geometry and sp2 hybridization of the radical centers.
Journal ArticleDOI
Disilenyllithium from Tetrasila-1,3-butadiene: A Silicon Analogue of a Vinyllithium
TL;DR: The reaction of dilithiosilane, (tBu2MeSi)2SiLi2 (2), with 1,1,2,2-tetrachloro-1, 2-dimesityldisilane produced the tetrasila-1-3-butadiene derivative (tbu2meSi2SiSi(Mes)(Mes)SiSiSi (SiMetBu2)2 (3; Mes = 2,4,6-trimethylphenyl) as reddish purple crystals as mentioned in this paper.
