Stereochemistry of the glutathione-dependent biotransformation of vicinal-dihaloalkanes to alkenes.

Drug Metab. Dispos. 10(3) , 201-4, (1982)

The stereochemistry of the metabolism of vic-dihaloalkanes to alkenes has been studied. This glutathione-dependent biotransformation may occur by two mechanism. The first mechanism involves the nucleo...
