Stoichiometric or catalytic quantities of simple 2° amines greatly increase the rate of HâZn exchange between ZnPh2 and a range of relatively non-acidic substrates, allowing for the convenient and direct preparation of α-functionalized organozincs.
化学计量或催化量的简单2°胺极大地提高了ZnPh2与一系列相对非酸性底物之间的H-Zn交换速率,从而可以方便、直接地制备α-功能化
有机锌。
