Covalently bonded compounds of heavy group 15/16 elements – Synthesis, structure and potential application in material sciences

Exploration of metal sulfide syntheses and the dissolution process of antimony sulfide in phosphonium-based ionic liquids

“…The chemistry of chalcogens and metal chalcogenides in ILs is manifold and gained a lot of interest in recent years. 1,4,6,22–26 Boros et al showed the dissolution of non-metallic solid elements in ILs, in particular the dissolution of sulfur in trihexyltetradecylphosphonium decanoate, [P 66614 ][dec], in which sulfur is highly soluble. The dissolved sulfur species shows a concentration dependency between [S 3 ]˙ − and [S 6 ] 2− , were the latter one occurs at higher concentrations.…”

“…22,23,27–30 Among them, the most prominent compound contains the supersphere anion [Ge 24 Sn 36 Se 132 ]. 24–31,32 But also a new modification of K 2 Sn 2 S 5 was accessible, which obviously does not include the IL used. 33…”

The Layered Semiconductor Cu(Sb2S3)[AlCl4]

“…One approach is to use precursors. [20][21][22][23][24][25][26][27][28][29] These are often expensive and the atom efficiency is not very high. Starting from the elements, or better yet directly from the ores from which they are extracted, and exploiting their solubility in ILs opens a path to more sustainable chemistry.…”

Transition-Metal-Catalyzed Diarylation of Isocyanides with Triarylbismuthines for the Selective Synthesis of Imine Derivatives

“…As the chemistry of heteroatom-containing compounds has significantly grown in recent decades, the properties and reactivities of high-period elements have gradually attracted more attention [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 ]. Bismuth is the heaviest of the group 15 elements, and its organic and inorganic compounds are regarded to be nontoxic [ 13 ].…”
