Abstract

For the first step of the bacterial transformation of chlorobenzene derivatives there are two possibilities: (1) formation of a dioxetane by a dioxygenase attack, (2) formation of an oxirane by a monooxygenase attack. Evidence for a monooxygenase attack is the conversion of 1,2-dichlorobenzene into 2,3-, 3,4- and 2,6-dichlorophenol, as is also the formation of 2,4,6-trichlorophenol from 1,3,5-trichlorobenzene.
