Synthesis of Aryl Thiocyanates and Aryl Selenocyanates via Visible‐Light Activation of Arylazo Sulfones

open access: yesAdvanced Synthesis and Catalysis, 2023
Two visible-light mediated protocols (based on a copper photoredox catalyzed and on a photochemical reaction, respectively) for the preparation of aryl thiocyanates and aryl selenocyanates from arylazo sulfones are presented herein, by exploiting ...

Selectfluor™: a novel and efficient reagent for the synthesis of β-hydroxy thiocyanates

open access: yesTetrahedron Letters, 2004
A variety of epoxides undergo rapid ring opening with ammonium thiocyanate in the presence of 10 mol % Selectfluor™ in acetonitrile at room temperature to afford the corresponding β-hydroxy thiocyanates in excellent yields with high ...

Tin(II) thiocyanate and complex thiocyanates

Journal of the Chemical Society A: Inorganic, Physical, Theoretical, 1969
The preparation and properties of pure tin(II) thiocyanate and of several complex thiocyanates are described. Their infrared spectra are discussed and evidence is adduced for mainly N-bonding of the thiocyanate, with extensive bridging in Sn(NCS)2. Tin(II) thiocyanate is found to form ether adducts of poor stability and to be an effective catalyst for ...

A Review on Thiocyanation of Indoles

Current Organic Synthesis, 2021
Background: The thiocyanation of indoles is a direct way for carbon-sulfur bond formation to access 3-thiocyanato-indoles. 3-thiocyanato-indoles exhibit potent biological and pharmacological activities and also serve as building blocks to synthesize many biologically active sulfur-containing indole derivatives.

Diphenylantimony(III) thiocyanate: unusual thiocyanate bridging

Journal of the Chemical Society, Chemical Communications, 1991
The thiocyanate group can bond via sulphur or nitrogen or bridge between two centres, but in diphenylantimony thiocyanate, unusual bridging gives antimony atoms coordinated by, respectively, two sulphur atoms, two nitrogen atoms and one atom of each type, allowing development of a curious infinite ‘triangular spiral’ structure in the solid state.

Thiocyanate and thiosulfate

1987
Publisher Summary This chapter discusses about the determination of thiocyanate and thiosulfate. Several methods are used for the analytical determination of inorganic thiocyanate. These include procedures based on the formation of colored complexes, either with ferric ions or with cupric ions and pyridine, or on oxidation with bromine followed by ...
