Preparations Alkylzinc iodides (RZnI) • Rieke metals • More recent reports emphasize the use of the less hazardous lithium metal in place of potassium.[2] Among the many metals that have been generated by this method are Mg, Ca, Ti, Fe, Co, Ni, Cu, Zn, In. • In some cases the reaction is carried out with a catalytic amount of an electron carrier such as biphenyl or naphthalene. The coprecipitated alkali metal chloride is usually not separated from the highly reactive metal, which is generally used in situ.
Preparations Dialkylzinc (R 2 Zn) • Unfunctionalized dialkylzincs (R 2 Zn) are obtained by transmetalation of zinc halides, such as ZnCl 2 , with organolithium or Grignard reagents. • Iodide-zinc exchange reactions catalyzed by CuI provide a practical way for preparing functionalized dialkylzincs. • Diorganozincs are always monomeric, the organozinc halides form aggregates through halogen bridges very much like Grignard reagents and also like Grignards they display a Schlenk equilibrium
