Convenient synthesis of diene–zirconocenes and regioselective partial reduction of the more highly substituted double bonds of conjugated dienes via complexation with zirconocenes and protonolysis
Stoichiometric reactions of nonconjugated dienes with zirconocene derivatives. Further delineation of the scope of bicyclization and observation of novel multipositional alkene regioisomerization
摘要:
The reaction of n-Bu(2)ZrCp(2) with nonconjugated dienes containing substituted vinyl groups can lead to either bicyclization or the formation of conjugated diene-zirconocenes via multipositional regioisomerization.
