Mild, Safe, and Versatile Reagents for (CF2)n Transfer and the Construction of Fluoroalkyl-Containing Rings

The preparation of new dizinc reagents [(MeCN)2­Zn­((CF2)n)2­Zn­(MeCN)2] (n = 3, 4, and 6) is reported. We show that the C4 reagent can readily transmetalate nickel to form a mononuclear perfluoronickelacycle. We also demonstrate that the reagents can be used to prepare novel fluoroorganics containing either perfluoroalkyl ring systems or perfluoroalkyl linked arenes under relatively mild conditions.
