Procedure

1,3-Dichloro-3-methyl-butane was reacted with 1,1-dichloroethene in the presence of aluminum chloride in the temperature range between -10° and +5° C. 3,3-Dimethyl-1,1,5-trichloro-1-pentene was thereby obtained and was purified by distillation. 1,1-Dichloro-3,3-dimethyl-1,4-pentadiene was obtained by splitting off hydrogen chloride with quinoline in the temperature range between 200° and 240° C. (See Application Ser. No. 281,614 filed July 9, 1981 now pending, corresponding to German Patent Application No. P 30 29 270.7 of 1.8.1980). ##STR6##
