## Abstract An (__E__)/(__Z)__ mixture (3โ€‰:โ€‰2) of 7โ€benzylidenecyclooctaโ€1,3,5โ€triene (**5**) is obtained when 1โ€benzylcyclooctaโ€1,3,5,7โ€tetraene (**7**), prepared by an improved procedure, is treated with __t__โ€BuOK in THF. Alternatively, a __ca.__ 9โ€‰:โ€‰1 mixture (__E__)/(__Z__)โ€**5** can be prepar
