Organic Cation and Complex Cation‐Stabilized (Poly‐)Selenides, [Cation]x(Sey)z: Diversity in Structures and Properties

“…[3] Especially for in situ generation of selenides, which are immediately consumed by subsequent reactions, a broad variety of methods has been used, such as ultrasound-induced electrochemical synthesis, [24] pulse radiolysis in saturated aqueous N 2 O solutions, which resulted in the interim formation of (Se 2 ) 2-and the formation of short- [29] (NMe 4 )(HSe) (c), [30] and Na 2 Se·xH 2 O with x = 5 [31] or 9 [32] 3 )] 2 (Se 2 ) (b) has been the only known organic cation-stabilized diselenide so far, yet with Li-Se distances as short as 2.561 Å, hence shorter than the sum of Li(+I) and Se(-II) ionic radii (2.57 Å). [33] In combination with an only threefold coordination of the Li + ion, this compound would probably be classified as a selenidolithiate.…”

Evolution of Principle and Practice of Electrodeposited Thin Film: A Review on Effect of Temperature and Sonication

“…The benefits of coupling ultrasound to electrochemical processes have been recognized and explored for a long time [51][52][53][54][55][56][57][58]. The complexity of the processes induced by power ultrasound [59,60] and the sensitivity of results on conditions and experimental parameters [61] have hitherto prevented ultrasound in electrochemistry, or sonoelectrochemistry, from becoming a reliable and established tool.…”

Synthesis of organochalcogen compounds in basic reducing systems

“…54 The RYanions are also generated elec trochemically from organic dichalcogenides 55 and used in the OCC synthesis. The reduction at the cathode is accompanied by an increase in the рH, i.e., a basic reduc ing system is formed directly in the process of electrolysis.…”
