Isomerization of the cis, trans isomers of 1,2,5,6- tetrasubstituted-1,5- cyclooctadienes to the corresponding cis, cis- isomers

摘要

Isomerization of the cis,trans isomers of 1,2,5,6- tetrasubstituted-1,5- cyclooctadienes to the corresponding cis,cis- isomers is carried out by contacting the cis,trans isomers with a halogen promoter in the presence of a suitable solvent in the absence of light.
