(アレーン) クロム錯体を利用した有機合成

抄録

(η⁶-Arene) chromium complexes have some characteristic properties due to the strong electron withdrawing ability and steric bulkiness of tricarbonyl chromium group. Their signficant applications have been developed utilizing following effects; 1) nucleophilic addition to the arene ring, 2) lithiation of the aromatic hydrogen, 3) stabilization of benzylic carbanion, 4) stabilization of benzylic carbocation, and 5) steric hindrance of Cr (CO)₃ group. Also, (arene) chromium complexes can exist in two enantiomeric forms, when the phenyl ring is substituted at ortho- or meta-position by different substituents. This review focuses on our investigations and the related works of (η⁶-arene) chromium complexes in organic synthesis.
