The present invention provides a method of making fulvenes, particularly 6-aryl-6-alkylfulvenes, 6-aryl-6-alkenylfulvenes, and related compounds, by combining alkyl- or alkenyl-arylketones with magnesium cyclopentadienyl reagents in nonprotic, including ethereal, solvents. The use of these compounds in preparing bis(cyclopentadienyl)methanes and related compounds, and ansa-metallocenes, is disclosed.
本发明提供了一种制备富烯的方法,特别是6-芳基-6-烷基富烯,6-芳基-6-烯基富烯和相关化合物的方法,通过将烷基或烯基-芳基酮与镁环戊二烯基试剂在非质子性溶剂中(包括醚类溶剂)结合使用来实现。本发明还揭示了这些化合物在制备双(环戊二烯基)甲烷和相关化合物以及ansa-金属茂的过程中的应用。
