Conclusions
-
1.
The catalytic dehydrochlorination of compounds of general formula CH3CCl2CH2CHClX (X = H, Cl, CH3) under the influence of Friedel-Crafts catalysts is accomplished via the chlorine of the dichloromethylene group toward both the methyl and the methylene groups.
-
2.
The alkaline dehydrochlorination of the same compounds proceeds with the involvement of the hydrogen of the methylene group and the chlorine of both chlorine-containing groups.
