air-stable, homogeneous, nickel catalyst that performs dehydrogenative cross-coupling reaction between secondary and primary alcohols to result α-alkylated ketone products selectively. The sequence of steps involve in this one-pot reaction is dehydrogenation of both alcohols, condensation between the ketone and the aldehyde, and hydrogenation of the in situ-generated α,β-unsaturated ketone. Preliminary
在此,我们描述了一种可分离的、空气稳定的、均相的镍催化剂,该催化剂在仲醇和伯醇之间进行脱氢交叉偶联反应,以选择性地产生 α-烷基化酮产物。该一锅反应中涉及的步骤顺序是两种醇的脱氢、酮和醛之间的缩合以及原位生成的 α,β-不饱和酮的氢化。初步的机理研究暗示了借氢反应后的激进机制。
