Insertion of Thiocyanogen into a PC Bond and Subsequent Formation of Polysulfide Derivatives

Abstract

Die Insertion von Thiocyanogen in die P‐C‐Bindung des Mangankomplexes 1 ([Mn]=[Mn(CNtBu)(CO)3]) verläuft nicht wie erwartet: Die S‐S‐Bindung bleibt im Produkt 2 erhalten. Verbindung 2 ist ein nützliches Reagens für die Synthese der neuartigen Dimetall‐Polysulfid‐Derivate 3 a–c (n=2–4).

Controlled Insertion Reaction of Thiirane into Carbamothioate: Novel Synthesis of Well-Defined Polysulfide

“…The characteristic physical properties of sulfur-containing polymers, such as polysulfides, polysulfoxides, polysulfones, polydisulfides, and polythioesters, have led to the application of these polymers in various functional materials, including high-refractive-index materials, conductive materials, coatings, sealants, and adhesives . Polysulfides can be synthesized by ring-opening polymerization and polyaddition.…”

Entropy and complexity analysis of the $$D$$ D -dimensional rigid rotator and hyperspherical harmonics

“…This complexity measure quantifies wiggliness or gradient content of the density jointly with its total extent all over the hyperspace, the parameter q weighting different regions of ρ( r). The special case q → 1 of (10) leads to the Fisher-Shannon complexity as The LMC complexity of ρ( r) is given [42,43] by…”

Copper‐Catalyzed Domino Cyclization/Thiocyanation of Unactivated Olefins: Access to SCN‐Containing Pyrazolines

“…[10] Moreover, thiocyanates are versatile building blocks that can be readily converted into heterocycles [11] and other sulfur-based compounds, such as thiols, [12] thioethers, [13] disulfides, [14] thiocarbamates, [15] isothiocyanates, [16] and trifluoromethylthiolates. [17] Therefore, direct and straightforward methods for the preparation of organothiocyanates, [18][19][20] especially with simple, cheap, and commercially available thiocyanating agents, are of great interest in organic synthesis. In this context, examples that could construct valuable heterocycles via cascade difunctionalization/cyclization of alkenes are scarce.…”

“…Further screening of bases showed that NaHCO 3 was the best one (Table 1, entry 11 and entries [16][17][18]. It was found that DMF, CH 3 CN, and 1,4-dioxane were also suitable solvents for this transformation, albeit with lower yields than DMSO (Table 1, entry 11 and entries [19][20][21].…”
