The assignments of the signals located at 7.97 to 8.00 and 8.06 in CDCl₃ were incorrect in Figure 2 on p 10228. They should be corrected as follows. Figure 2. Compound 2a in DMSO-d₆ and CDCl₃. Comparison of aminal 2a dissolved in DMSO-d₆ (top) and CDCl₃ (bottom) is shown. When aminal 2a is dissolved in DMSO-d₆, the equilibrium is shifted heavily toward aminal 2a, allowing for the observation of aminal 2a. When aminal 2a is dissolved in CDCl₃, the equilibrium is shifted heavily toward imine 2a′ and 2-aminopyridine, allowing for the clear observation of both imine 2a′ (blue triangles) and 2-aminopyridine (red circles).

对“NHC 催化的 N,N'-Dipyridin-2-yl Aminals 与醛的 Aza-Benzoin 缩合反应”的修正

在第 10228 页的图 2中，CDCl ₃中位于 7.97 到 8.00 和 8.06 的信号的分配不正确。它们应按如下方式更正。图 2. DMSO- d ₆和CDCl _{3 中的}化合物2a。显示了溶解在 DMSO- d ₆（顶部）和 CDCl ₃（底部）中的氨基2a 的比较。当 aminal 2a溶解在 DMSO- d _{6 中时}，平衡向 aminal 2a移动，允许观察 aminal 2a。当氨基2a溶解在 CDCl _{3 中时}，平衡向亚胺2a'和 2-氨基吡啶严重移动，从而可以清楚地观察亚胺2a'（蓝色三角形）和 2-氨基吡啶（红色圆圈）。这篇文章还没有被其他出版物引用。图 2.
