The reaction of an optically active cyclopentadienyl salt, formed from the asymmetric reduction of 6-methyl-6-phenylfulvene, with Mo(CO)6 followed by treatment with N-methyl-N-nitroso-p-toluenesulfonamide, yields an optically active organomolybdenum compl

Paragraph 0090; 0091; 0092, (2017/11/30)
The invention relates to a preparation method of a substituted cyclopentadienyl metallocene compound. The preparation method comprises the following steps that a cyclopentadienyl compound and an aldehyde-ketone compound are adopted to carry out reaction to produce a fulvene compound, then the fulvene compound is acted with metal hydride to produce substituted cyclopentadienyl salt, and the substituted cyclopentadienyl salt is further reacted with group IV metal halide to produce the metallocene compound. Compared with the prior art, the preparation method has the advantages of high product yield, convenience in operation, good economy and the like and is suitable for industrial production.
An improved pathway to 6,6-disubstituted fulvenes
Chajara, Khalil,Ottosson, Henrik
, p. 6741 - 6744 (2007/10/03)
Pentafulvenes with alkyl and/or aryl substituents at the exocyclic position are formed rapidly in high yields through reaction of crystalline sodium cyclopentadienide directly with the appropriate ketones.
