The synthetically most widely used and useful reaction of chlorobis(η5-cyclopentadienyl)hydridozirconium(IV) (53) and other related zirconium hydrides is hydrozirconation of alkenes and alkynes to produce the corresponding chlorobis(η5-cyclopentadienyl)monoorganozirconium complexes, where the monoorgano group is an alkyl or alkenyl group, respectively (Section 2.11.4.6.1.1). Several extensive reviews on this topic have been reported.[18,91,92] Bis(η5-cyclopentadienyl)hydridozirconium derivatives also react with a wide variety of other functional groups. These reactions are important both as a means of reducing organic functional groups and for suppressing unwanted side reactions in the hydrozirconation of alkenes and alkynes (Section 2.11.4.6.1.2). As stoichiometric reagents for organic synthesis, preformed and pure chlorobis(η5-cyclopentadienyl)hydridozirconium(IV) (53), in situ generated chlorobis(η5-cyclopentadienyl)hydridozirconium(IV) (53) and related reagents, and in situ generated chlorobis(η5-cyclopentadienyl)isobutylzirconium(IV) (57) have been most frequently used. However, other complexes, such as bis(η5-cyclopentadienyl)dihydridozirconium(IV) (52) and bis(η5-pentymethylcyclopentadienyl)dihydridozirconium(IV) (56),[93] may find a wide range of applications in the future.
