Cover Picture: Theoretical Study on the Halogen-Zinc Exchange Reaction by Using Organozincate Compounds (Chem. Eur. J. 23/2009)

Density functional theory and fragment-energy analysis have been used to probe the mechanism of the halogen–zinc exchange reaction. In their Full Paper on page 5686 ff., M. Uchiyama, S. Nakamura et al. discuss three important factors in this reaction: The effect of the halogen species, the effect of the alkyl ligand on zinc, and the effect of the substrate nature.
