Abstract
A process for dehalogenating halogenated organic compounds comprising: (1) combining in an electrochemical cell (a)(i) a halogenated organic compound or (ii) a solid or fluid containing a halogenated organic compound with (b) a compound capable of forming an iminium ion having the formula (I) ##STR1## wherein X represents an oxygen atom or a sulfur atom, R.sub.1 and R.sub.2, which may be the same or different, each represents an alkyl group, an aryl group or a heterocyclic group, and R.sub.1 and R.sub.2 may combine and form a carbocyclic ring or a heterocyclic ring, and R.sub.3 represents a hydrogen atom, an alkyl group, an aryl group, a heterocyclic group or a halogen atom, and (2) applying an electrical voltage and an electrical current to an electrode of the electrochemical cell as a working electrode; which voltage is such that a reaction occurs and the halogenated organic compound is partially or completely dehalogenated.
