Unusual anions [LAI(SH)(S)](-) and [LAI(S)(2)](2-) stabilized by weakly coordinating imidazoliurn cations. Synthesis of LAI(SSiMe2)(2)O (L HC[C(Me)N(Ar)](2), Ar=2,6-iPr(2)C(6)H(3))
Deprotonation of an Al-SH moiety has been achieved easily by using N-heterocyclic carbene as the base. Monomeric mono- and bis-imidazolium salts [CtH+][LAI(SH)(S)](-) ([CtH+] = N,N'-bis-tert-butylimidazolium), [CmH+][LAI(SH)(S)](-), and [CmH+](2)[LAI(S)(2)](2) ([CmH+] = N,N'-bismesitylimidazolium), containing unusual anions [LAI(SH)(S)](-) and [LAI(S)(2)](2-), have been synthesized in nearly quantitative yields, Furthermore, [CmH+](2)[LAI(S)(2)](2) has been successfully used for the preparation of LAI(SSiMe2)(2)O containing the [O(Me2SiS)(2)](2-) ligand.
