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.
手性二级格氏试剂向 Cu(I) 或 Mn(II) 的金属转移以部分外消旋化的方式发生,这表明了两个金属转移循环的顺序,一个是外消旋化(由 ET 引起),另一个是(主要)配置的保留。
