Abstract
is isomerised to 3,4-dichlorobutene-1 or vice versa by contact with a catalyst contg. >=1 Cu cpds e.g. salts of org. mineral acids or complexes e.g. cupric naphthenate, and 0.5-10 wt.% based on total dichlorobutenes of an org. sulphide at 80-160 degrees C pref. 100-130 degrees C. The sulphide is R-S-R' (or functional derivs) where R and R' are alkyl, aryl or alkaryl or form together a cyclic nucleus. Speed of reaction is improved.
