Stereochemistry of reductive dehalogenation with deuterium gas

Journal of Labelled Compounds and Radiopharmaceuticals, 1986
AbstractThe stereochemistry of reductive debromination and deiodination of 4‐haloprolines and 2‐ or 7‐bromo‐cholesterols with 2H2 catalyzed by Pd was investigated using 2H NMR. The reactions are stereoselective but not stereospecific.

Catalytic reductive dehalogenation of thiophene derivatives

Chemistry of Heterocyclic Compounds, 1982
A method for the preparation of 3-substituted derivatives of thiophene by reductive dehalogenation of 2,5-dihalo-substituted thiophenes in the presence of a palladium complex is proposed. The dehalogenation reaction is a stepwise process. The presence of an acyl group in the 3 position increases the rate of the process.

Reductive dehalogenation of 2-iodobenzothiazole with alkanethiols

Journal of the Chemical Society, Perkin Transactions 2, 1976
The reactions of 2-iodobenzothiazole with alkanethiols in methanol afford the unsubstituted benzothiazole as previously found for reactions with thiophenols. The reaction is autocatalytic, the hydroiodic acid produced being responsible for this phenomenon. A mechanism for the reaction is suggested.

Inhibitory Effects of Corticoids on Reductive Halothane Dehalogenation

Drug Metabolism and Drug Interactions, 1995
The effects of corticoids, hydrocortisone, methylprednisolone, betamethasone and dexamethasone, on the reductive metabolism of halothane to produce chloro-difluoroethylene (CDE) and chlorotrifluoroethane (CTE) in the liver microsomes of guinea-pig were examined.

Reductive dehalogenation of polyhalofluorocarbons with tributyltin hydride

Journal of Fluorine Chemistry, 1995
Abstract The reduction of polyhalofluorocarbons, including ClCF2CFClCF2Cl, (ClCF2CFCl)2, ICH2(CF2)3CH2I and vicinal dichloro-perfluorocycloalkanes, with tributyltin hydride gave the corresponding hydrofluorocarbons in good to excellent yield. The results are compared with similar reductions with other reducing agents, and to tin hydride reductions of

Reductive dehalogenation: A subsurface bioremediation process

Remediation Journal, 1990
AbstractIntroduction and large‐scale production of synthetic halogenated organic chemicals over the last fifty years has resulted in a group of contaminants that tend to persist in the environment and resist both biotic and abiotic degradation. The low solubility of these types of contaminants, along with their toxicity and tendency to accumulate in ...

Reductive catalytic dehalogenation of light chlorocarbons

Applied Catalysis B: Environmental, 1999
Abstract Several palladium and platinum supported catalysts have been employed in the gas-phase dehalogenation of chloromethanes (CCl4, CHCl3 and CH2Cl2) and chlorobenzene by using molecular hydrogen under mild conditions. A new porous glass material (Vycor) has been found to be a promising carrier for platinum in the selective hydrogenation of CCl4
