5,5-Diphenyl-2-thiohydantoin

Acta Crystallographica Section C Crystal Structure Communications, 1998
The molecular structure of the title compound, 5,5-diphenyl-2-thioxoimidazolidin-4-one, C 15 H 12 N 2 OS, resembles that of 5,5-diphenylhydantoin (phenytoin). The C=S distance is 1.648 (2) A. The crystal structure consists of ribbon-like infinite sheets of molecules bonded by N-H...O and N-H...S hydrogen bonds.

Copper(I) halide complexes of 2-thiohydantoin and 5,5-diphenyl-2-thiohydantoin

Polyhedron, 2012
Abstract A series of copper(I) halide complexes formulated as [CuX(L)2] [X = Cl, Br; L = 2-thiohydantoin (th) and 5,5-diphenyl-2-thiohydantoin (dpth)] were prepared and their photophysical and thermal (TG–DTA) behaviour was investigated. Further treatment of these complexes with triphenylphosphane gave mixed-ligand compounds [CuX(L)(PPh3)2 ...

Acidity function 'failure.' I. 2-Thiohydantoins

Canadian Journal of Chemistry, 1979
The protonation of 2-thiohydantoin and of eight derivatives variously substituted at the 1-, 3-, and 5-positions with alkyl groups or a single phenyl followed h0 (Cox–Yates m* ∼ 1.1); however, the protonation of 3,5-diphenyl-2-thiohydantoin followed hT (m* = 1.50), and of 5,5-diphenyl-2-thiohydantoin an acidity function intermediate between h0 and hT (

Derivatives of 2-thiohydantoin as spectrophotometric analytical reagents

Talanta, 1978
The synthesis, characteristics, properties and reaction with metallic ions of four pyridine derivatives of 2-thiohydantoin have been studied. 5-(2-Pyridyl)methylene-2-thiohydantoin, 5-(6-methyl-2-pyridyl) methylene-2-thiohydantoin, 5-(di-2-pyridyl)methylene-2-thiohydantoin and 5-[1-(2-pyridyl)-1-methyl] methylene-2-thiohydantoin have been synthesized ...

5,5-Diaryl-2-thiohydantoins and 5,5-diaryl N3-substituted 2-thiohydantoins as potential hypolipidemic agents

Journal of Medicinal Chemistry, 1986
A series of 5,5-diaryl-2-thiohydantoins and 5,5-diaryl-N3-substituted-2-thiohydantoins related to 5,5-diphenyl-2-thiohydantoin (DPTH) were investigated as potential hypolipidemic agents with the goal of increased potency over DPTH itself. In the 5,5-diaryl class, the best results were obtained by substituting two pyridyl rings for the phenyl rings ...

Fused 2‐Thiohydantoin Derivatives: Evaluation as Potential Antioxidants

Archiv der Pharmazie, 1997
AbstractA series of fused 5,5‐diphenyl and 5‐arylidene‐2‐thiohydantoin derivatives were examined for their oxygen free radical inhibitory and radical scavenging properties (RSC) using both an enzymic and non‐enzymic biological generators of free radicals.

Synthesis of 3‐Ω‐Amino‐2‐thiohydantoins.

ChemInform, 2003
AbstractIn the reaction of ethyl isothiocyanatoacetate with diamines, followed by cyclization of the intermediate product, 3‐monosubstituted thiohydantoins have been obtained. It was found that the reaction course depends on the purity of the isothiocyanate used and also, in the case of dialkylaminoamines, the self‐cyclization occurs.
