钛族配合物在有机合成中应用的新进展

Recent developments of the applications of group Ⅳ metal complexes in organic synthesis

综述了近年来钛族配合物在有机合成中应用的新进展。包括高立体选择性和化学选择性进行催化氢化、还原、开环、环化、酰胺化，催化下格氏试剂与不饱和七、八元杂环高立体选择性的加成反应，格氏试剂对环状烯丙醇进行选择性加氢，炔锆配合物高化学选择性、立体选择性与醛反应，Ｃｐ２Ｚｒ（Ｈ）Ｃｌ与烯、炔加成生成亲核试剂，Ｃｐ２ＺｒＣｌ２／ＭＡＯ（Ａｌ／Ｚｒ为１∶１）催化烯烃齐聚等。

The recent developments of applications of group Ⅳ metal complexes in organic synthesis are reviewed,including highly chemical and stereo selective catalysis in hydrogenation,reduction,ring opening,cyclization and amidation by group Ⅳ complexes,selective addition of ethyl magnesium chloride to seven and eight membered rings,high regio and diastereo selective reaction of alkyne zirconocene complexes with aldehydes,addition of Cp 2Zr(H)Cl to alkenes and alkynes,catalytic oligomerization of α olefins and α,ω dienes with Cp 2ZrCl 2/MAO.
