Summary
-
1.
By the alkylation of t-alkyl chlorides with vinyl chloride in presence of metal halides the following dichloroalkanes were synthesized for the first time: 1,1-dichloro-3,3,4-trimethylpentane, 1,1-dichloro-3,3,4,4-trimethylpentane, 1,1-dichloro-3,3,5,5-tetramethylhexane.
-
2.
By the dehydrochlorination of 1,1-dichloralkanes over KOH in diethylene glycol monoacetylenic hydrocarbons containing quaternary carbon atoms were prepared for the first time.
-
3.
The following diacetylenic hydrocarbons were prepared for the first time by oxidative dimerization: 3,3,8,8-tetramethyl-4,6-decadiyne, 2,3,3,8,8,9-hexamethyl-4,6-decadiyne, 2,2,3,3,8,8,9,9-octamethyl-4,6-decadiyne, and 2,2,4,4,9,9,11,11-octamethyl-5,7-dodecadiyne.
