Trans-1 -Bromo-1 -hexene

Coupling reactions with vinyl halides are stereospecific. For example, reaction of trans-1 -bromo-1-hexene with (CH3)2CuLi forms rrara-2-heptene as the only stereoisomer (Equation [3]).

Lund and coworkers [131] pioneered the use of aromatic anion radicals as mediators in a study of the catalytic reduction of bromobenzene by the electrogenerated anion radical of chrysene. Other early investigations involved the catalytic reduction of 1-bromo- and 1-chlorobutane by the anion radicals of trans-stilhene and anthracene [132], of 1-chlorohexane and 6-chloro-l-hexene by the naphthalene anion radical [133], and of 1-chlorooctane by the phenanthrene anion radical [134]. Simonet and coworkers [135] pointed out that a catalytically formed alkyl radical can react with an aromatic anion radical to form an alkylated aromatic hydrocarbon. Additional, comparatively recent work has centered on electron transfer between aromatic anion radicals and l,2-dichloro-l,2-diphenylethane [136], on reductive coupling of tert-butyl bromide with azobenzene, quinoxaline, and anthracene [137], and on the reactions of aromatic anion radicals with substituted benzyl chlorides [138], with... 

Bromochlorination of olefins such as 1-hexene, ethylene, 3,4-dichloro-l-butene, trans-l,4-dichloro-2-butene and 3-chloro- and 3-bromo-propene has been accomplished using...
