“…Compound 3 is the first example of a stable silylium cation that comprises low-valent silicon substituents, although the chemistry of stable silylium cations has been studied in recent decades. [16] Compound 3 is soluble in THF, DME, and pyridine. It is stable in the solid state at room temperature under an inert atmosphere.…”

The synthesis and reactivity of a silyliumylidene cation stabilized by an amidinate ligand and 4-dimethylaminopyridine (DMAP) are described. The reaction of the amidinate silicon(I) dimer [LSi:]2 (1; L = PhC(NtBu)2) with one equivalent of N-trimethylsilyl-4-dimethylaminopyridinium triflate [4-NMe2C5H4NSiMe3]OTf and two equivalents of DMAP in THF afforded [LSi(DMAP)]OTf (2). The ambiphilic character of 2 is demonstrated from its reactivity. Treatment of 2 with 1 in THF afforded the disilylenylsilylium triflate [L'2(L)Si]OTf (3; L' = LSi:) with the displacement of DMAP. The reaction of 2 with [K{HB(iBu)3}] and elemental sulfur in THF afforded the silylsilylene [LSiSi(H){(NtBu)2C(H)Ph}] (4) and the base-stabilized silanethionium triflate [LSi(S)DMAP]OTf (5), respectively. Compounds 2, 3, and 5 have been characterized by X-ray crystallography.

“…[1] The isolation of such species at ambient temperature has generally required their pairing with large, charge diffuse, weakly coordinating anions (WCAs); while the highly electrophilic nature of the cations is at the heart of their remarkable reactivity. Despite considerable efforts, fewer advances have been made within the closely related field of Group 14 element(II) monocation (RED + ) chemistry, [2] and one-coordinate examples of these ions remain elusive.…”

“…1,2,3 In 1986, however, Jutzi and coworkers reported the isolation of decamethylsilicocene which was the first monomeric, divalent silicon(II) compound that was stable at room temperature. 4 The formally tencoordinate Si(η 5 -C5Me5)2 exists as two conformers; a centrosymmetric species with parallel C5Me5 rings or a bent form with a 25.3° interplanar angle.…”

Isolation of a Stable, Acyclic, Two-Coordinate Silylene

et al. 2012

The synthesis and characterization of a stable, acyclic two-coordinate silylene, Si(SArMe6 )2 [ArMe6 = C6H3-2,6(C6H2-2,4,6-Me3)2], by reduction of Br2Si(SArMe6 )2 with a magnesium(I) reductant is described. It features a V-shaped silicon coordination with a S–Si–S angle of 90.52(2)° and an average Si–S distance of 2.158(3) Å. Although it reacts readily with an alkyl halide, it does not react with hydrogen under ambient conditions, probably as a result of the ca. 4.3 eV energy difference between the frontier silicon lone pair and 3p orbitals.
