Stereochemistry of the transmetalation of Grignard reagents to copper (I) and manganese (II).

Reinhard W Hoffmann1, Bettina Hölzer.   

Abstract

Transmetalation of a chiral secondary Grignard reagent to Cu(I) or Mn(II) occurs with partial racemization in a manner that suggests the sequence of two transmetalation cycles, one with racemization (caused by ET ?) and the other one with (predominant) retention of configuration.
