In addition to the zirconium-catalyzed carboalumination reactions (Sections 2.11.4.7.6 and 2.11.4.7.6.2), other zirconium-catalyzed carbometalation reactions involving magnesium[193] and zinc have also been developed.[194,195] With the possible exception of the carbozincation of alkynes with dialkylzincs, such as diethylzinc(II), promoted by bis(η5-cyclopentadienyl)diiodozirconium(IV) (43, M = Zr), e.g. to give 149 (Scheme 69),[194] the carbomagnesation and carbozincation reactions of alkenes and alkynes have been shown to proceed via zirconium(II)–alkene or zirconium(II)–alkyne complexes, respectively. Therefore, they are discussed in Section 2.11.8.
