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.

Conjugated dienes can be initially converted to their zirconocene complexes most conveniently by their reaction with (C5H5)2ZrCl2 and freshly ground Mg; the resultant complexes can then be protonolysed with 3 mol dmâ3 HCl to give regioselectively monoenes corresponding to partial hydrogenation of the more highly substituted double bond.
