Chlorine-38 for chlorine substitution in geometric and diastereomeric compounds: mechanism and stereochemistry
… control the stereochemical course of the hot substitution reactions, the stereochemistry of the energetic ³⁸Cl for Cl was studied in diastereomeric 1,2-dichloro-1,2-difluoroethane and the geometric isomers of 1,2-dichlorohexa-fluorocyclobutane. In each system, the conformer population was …

On the stereochemical course of the chlorine-38 for chlorine substitution in diastereomeric and enantiomeric compounds
The stereochemistry of the energetic ³⁸Cl for Cl substitution was studied in diastereomeric 2,4-dichloropentane and 2,3-dichlorobutane as well as in enantiomeric 2-chloro-1-propanol in solution. It was found that the stereochemical course of the substitution reaction exhibits a strong dependence on …

Effects of Activated Carbon on Reactions of Free and Combined Chlorine With Phenols (Chlorination, Gac)
… treatment results in contact of free or combined chlorine with activated carbon, which is used to remove organic compounds from water. Free chlorine reacts with a group of phenols (phenol, guaiacol, catechol, 2,6-dimethoxyphenol, p-chlorophenol) in dilute aqueous solutions (10('-5)M), to produce …

Synthesis and characterization of 2-chloro-3-benzylthiopyrrolo[1,2-a]- benzimidazol-1-one and 2,3-di(benzylthio)pyrrolo[1,2-a]benzimidazol-1-one.
… benzimidazol-1-one as the major product. Chlorine substitution in 2,3-dichloropyrrolo[1,2-a]benzimidazol-1-one by added benzylthiol occurs in the presence of pyridine to provide the corresponding monosulfide and disulfide derivatives. The first benzylthiol ligand undergoes reaction at the …

The Reaction of Aqueous Free Chlorine With Organic Compounds Adsorbed on Granular Activated Carbon
The reaction of organic compounds with aqueous chlorine was examined before and after adsorption on an activated carbon bed. An extract of humic acid from peat soil was used as the organic compound in the first part of the study. The concentration of humic acid and chlorine were typical of those …
