The scope of the migratory insertion reactions of bis(η5-cyclopentadienyl)organozirconium derivatives with α-hetero-substituted organometals has been substantially expanded through the use of α-halo-substituted alkyl- and alkenyllithiums, such as those used in the formation of 516–521 (Scheme 186).[151,409] Some related reactions of bis(η5-cyclopentadienyl)organohafnium derivatives, which can also be used to give 516, and those of γ-haloalkynyllithiums, such as 522 used in the formation of allene 523 and enyne 524, are also noteworthy (Scheme 186).[151]
