Abstract

Polyfunctional organometallics of magnesium and zinc are readily prepared from organic halides via a direct metal insertion in the presence of LiCl or a Br/Mg-exchange using iPrMgCl center dot LiCl (turbo-Grignard) or related reagents. Alternatively, such functionalized organometallics are prepared by metalations with TMP-bases (TMP = 2,2,6,6-tetramethylpiperidyl). The scope of these methods is described as well as applications in new Co- or Fe-catalyzed cross-couplings or aminations. It is shown that the use of a continous flow set-up considerably expands the field of applications of these methods and further allows the preparation of highly reactive organosodium reagents.
