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.
摘要
手性二级格氏试剂向铜（I）或锰（II）的金属转移反应会发生部分外消旋化，其方式表明存在两个金属转移循环，一个伴有外消旋化（由电子转移引起？），另一个则（主要）构型保持。
