Transannular interactions in the chlorination of cis,cis-cyclo-octa-1,5-diene and cis-cyclo-octene with SbCl5
Abstract
The chlorinations of cis,cis-cyclo-octa-1,5-diene and cis-cyclo-octene with SbCl5 in CCl4 give endo- and exo-2-anti-8-dichlorobicyclo[3,2,1]octanes and cis- and trans-1,4-dichlorocyclo-octanes respectively in 70–80% yield.
