A new class of coinage-metal chalcogenide compounds [Au4M4(μ3-E)4(IPr)4] (M = Ag, Au; E = S, Se, Te) has been synthesized from the combination of N-heterocyclic carbene-ligated gold(I) trimethylsilylc

A high-yield synthesis of the class of (trimethylsilyl)chalcogenolate organic salts [Cat][TMS-E] (E = S, Se, Te; Cat = BMPyr, DMPyr, NMe4, nBu3MeP) is presented. The title compounds have been prepared by the strictly aprotic reaction between the respective bis(trimethylsilyl)chalcogenide (TMS2E) and methylcarbonate ionic liquids (ILs). This constitutes a novel reaction behavior of methylcarbonate ILs, acting as a nucleophilic desilylating agent and a Lewis base instead of as a Bronsted base. Thus prepared silylchalcogenolate salts represent an activated form of the multifunctional TMS2E reactant series. Pyrrolidinium TMS-S salts have proven to be excellent precursors for the synthesis of pyrrolidinium hexasulfides. The scope of the desilylation reaction can be extended to other silyl-bearing synthons such as (trimethylsilyl)azide and (trimethylsilyl)cyanide.
Bis(oligosilanyl)chalcogenides [Me3Si)xMe3-xSi]2E, alkalimetal oligosilanylchalcogenolates (Me3Si)xMe3-xSi-EMI and oligosilanylchalcogenols (Me3Si)xMe3-xSi-EH (E = S, Se, Te) syntheses and NMR study

Bis(oligosilanyl)chalcogenides [(Me3Si)x Me3-x Si]2E, alkalimetal oligosilanylchalcogenolates (Me3Si)x Me3-x Si-EMI and oligosilanylchalcogenols (Me3Si)x Me3-x Si-EH (x=1-3; E=S, Se, Te) were synthesized and characterized by 1H-, 13C-, 29Si-, 77Se- and 125Te-NMR spectroscopy. Trends of NMR parameters (chemical shifts, coupling constants) are discussed.
