Lithium tris(trimethylsilyl)silylselenolate mono(1,2-dimethoxyethane)

Synthesis of a Silylated Phosphorus Biradicaloid and Its Utilization in the Activation of Small Molecules

“…X‐ray structure analysis unequivocally revealed the existence of [Li(µ‐SeHyp)] 2 (C 4 H 10 O 2 ) 2 ( 6 ; Figure ). A similar tellurium species with THF as the stabilizing ligand at the Li centers was previously synthesized in 1992 (Scheme ), and a little later the selenium species was prepared by metathesis reaction . Additionally, the authors showed that THF can be replaced by DME simply by adding DME.…”

“…Additionally, the authors showed that THF can be replaced by DME simply by adding DME. As the structural parameters of 6 were already discussed before, we want to abstain from a detailed discussion here …”

Lithium Alkylselenolates and -tellurolates − A Solid-State and Solution Structural Study

“…The LiϪSeϪLi inter-ring angle is also very acute, 69.2(6) and 70.1(6)°in 1 cf. 77.0(2) and 75.8(4)°in the only other dimeric lithium selenolates [Li-(DME)SeSi(SiMe 3 ) 3 ] 2 [5] and [Li(bipy)(SePh)] 2 , [13] respectively. [10] and 2.122(2) Å in [CpFe{C 5 H 3 -(CH 2 NMe 2 )TeLi·DME}].…”

Salts of Tris(pentafluoroethyl)silylchalcogenolates [Si(C2F5)3E]− with E = S, Se, and Te: Synthesis, Structure, and Reactivity

“…Alkali-metal chalcogenolates M[SiR 3 E] (M = alkali metal) are generally prepared by deprotonation of the corresponding chalcogenols, SiR 3 EH, 3−6 or by cleavage of the Si−E bonds in bis-silylated chalcogenides, for example. 5,7−11 Here, mainly the thiolates 3,5,7 were considered in more detail, while the chemistry of the corresponding selenolates 12 and tellurolates 13 remained underdeveloped. 14 Recently, Sundermeyer et al described the syntheses of monomeric N,N-dimethylpyrrolidinium chalcogenolates [Me 2 Pyr][SiMe 3 E] with E = S, Se, and Te.…”
