Summary
-
1.
By the hydrogenation of 1,1,1,9-tetrachlorononane over palladium, 1.9,9,10,10,18-hexachlorooctadecane was synthesized. Under the action of zinc this hexachloro compound gave 1,9,10,18-tetrachloro-9-octadecene.
-
2.
Reaction of nucleophilic reagents with compounds of the type [Cl (CH2)n CCl =]2 gave the compounds X(CH2)nCCl=CCl(CH2)nCl (n=2,4, and 8) and X(CH2)n CCl=CCl(CH2)n X(n=4,6) X=CH3COO, OH, (C2H5)2N, CN, COOH, (C2H5)3.NI.

3.
1,3,4,6-Tetrachloro-3-hexene, unlike the saturated 1,3,3,4,4,6-hexachlorohexane and 1,1,1,3-tetrachloropropane, undergoes exchange reactions with nucleophilic reagents, but these reactions proceed less readily than those with higher tetrachloroalkenes.
