摘要: 二氯二茂锆同异丁基格氏试剂以1:2摩尔比反应,于室温下生成有机锆中间体,后者同烯烃、炔烃或二烯反应,最后生成还原的二聚物或分子内环化产物。

关键词: 二氯二茂锆, 格氏试剂, 烯烃, 二烯烃, 催化作用

Abstract: Treatment of Cp2ZrCl2 with 2 equivalent of i-Br.MgBr Grignard reagent in THFat room temperature produces organo-zirconium species that react with alkenes, alkynes or diencs, ending up with reductive dimers or intramolecular cyclization products.

Key words: Bis(cyclopentadienyl)zirconiumdichloride, Grignard reagent, Alkenes, Alkadienes, Catalysis
