Generation and Oligomerization of Bicyclooctyne and Properties of Tris(bicycloocteno)benzene Obtained from the Linear Trimer
Reaction of 2,3-dibromobicyclooct-2-ene (10) with n-butyllithium in THF at -78 deg C affords a series of oligomeric dibromides 11 (n = 2-5), which are composed of linearly bonded bicyclooct-2-ene units.A trapping experiment indicated that th
