Catalytic dehydrohalogenation of dihaloalkanes with Fe(III) and its mechani
sm has been investigated. Damped oscillations of the reaction mixture were
observed when the reactions were carried out at 50 degrees C in evacuated s
ystems. We have described the main features of this behavior taking into ac
count the organometallic intermediates, the reversibility of the reaction a
nd the catalyst transformation. (C) 2000 Published by Elsevier Science Ltd.
