摘 要：正 β-Hydride abstraction is one of the fundamental reactions of organometallic compounds and has been accepted as one of the most attractive approaches in synthetic chemistry. The β-hydrogen of linear alkyl groups in organometallic compounds as 1 easily undergo β-hydride abstraction （eq 1）. The type of β-hydrogen in bicyclicorganometallic compounds 2 is also known to undergo abstraction reactions （eq 2）. However, although the type of bicyclicorganometallic compounds 3 can be readily prepared and have been used in organic synthesis. P-hydride abstraction from the α-positioned alkyl groups has not been reported.
