Conclusions
-
1.
The alkaline dehydrochlorination of some polychloroalkenes and 1, 1, 3, 3, 5-pentachloropentane in ethylcellosolve medium at 20–40° gave five previously unknown conjugated dienes that represent chlorinated homologs of chloroprene.
-
2.
The stereochemistry of the dienes was studied employing IR and NMR spectroscopy, and also GLC. In the case of the cis-form the NMR signal from the H2 proton in the investigated dienes is shifted downfield by ~0.3 ppm when compared with the trans-form, which makes it possible to judge the ratio of the isomers in the obtained products.
