Article abstract of DOI:10.1246/bcsj.60.797

Reaction of cis- with a slight excess of mesityllithium in benzene-ether mixture afforded trans- (Mes=2,4,6-trimethylphenyl; SEt2=diethyl sulfide) as a major product.When mesityllithium reagent containing lithium bromide was used, trans- was obtained.Acceleration of cis-trans isomerization in the presence of mesityllithium was observed.
