Nazish, Mohd; Legendre, Christina M.; Sarkar, Samir Kumar; Luecken, Jana; Goffitzer, Daniel J.; Diefenbach, Martin; Schwederski, Brigitte; Herbst-Irmer, Regine; Stalke, Dietmar; Holthausen, Max C.; Kaim, Wolfgang; Roesky, Herbert W. published the article 《Selective Route to Stable Silicon-Boron Radicals and Their Corresponding Cations》. Keywords: stable silicon boron radical cation preparation crystal mol structure; mol structure calculation electrochem redox silicon boron radical cation.They researched the compound: Silver(I) trifluoromethanesulfonate( cas:2923-28-6 ).Formula: CAgF3O3S. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:2923-28-6) here.
Herein, authors report on a facile and selective one-pot synthetic route to silicon-boron radicals. Reduction of Br2BTip (Tip = 2,4,6-iPrC6H2) with KC8 in the presence of LSi-R affords LSi(tBu)-B(Br)Tip (1) and LSi(N(TMS)2)-B(Br)Tip (2) [L = PhC(NtBu)2]. These first examples of silicon-boron isolated radical species feature spin d. on the silicon and boron atoms. 1 And 2 exhibit extraordinary stability to high temperatures under inert conditions in solution and air stability in the solid state. Both radicals have been isolated and fully characterized by ESR spectroscopy, SQUID magnetometry, mass spectrometry, cyclic voltammetry, single-crystal x-ray structure anal., and d. functional theory calculations Moreover, compound 1 exhibits one-electron transfer when treated with 1 equivalent of AgSO3CF3 and [Ph3C]+[B(C6F5)4]-, resp., resulting in the corresponding cations [LSi(tBu)-B(Br)Tip]+[CF3SO3]- (3) and [LSi(tBu)-B(Br)Tip]+[B(C6F5)4]- (4). Compounds 3 and 4 have been characterized with multinuclear NMR and mass spectrometry.
I hope my short article helps more people learn about this compound(Silver(I) trifluoromethanesulfonate)Formula: CAgF3O3S. Apart from the compound(2923-28-6), you can read my other articles to know other related compounds.
