Transmetalation functionalized Grignard reagents

On the other hand, a transmetallation of Grignard reagent 69 to the corresponding copper derivative with CuCN-2LiCl [49] leads to the formation of the diamino derivative 297 in 65% yield (Scheme 4.62). Besides this, several other reagents are known that allow the formal oxidation of a Grignard reagent to an amino function and their use has been excellently reviewed elsewhere [144]. [Pg.149]

Unfunctionalized dialkylzincs (R2Zn) are obtained by transmetalation of zinc halides, such as ZnCl2, with organolithium or Grignard reagents. Iodide-zinc exchange reaetions catalyzed by Cul provide a practical way for preparing functionalized dialkylzincs. [Pg.300]
