    脂肪族酰胺的选择性α-氧化和羟基化
    摘要:
    与醛,酮,甚至酯的α-官能化相比,酰胺的直接α-改性仍然是一个挑战,因为α-CH基团的酸度较低。NH(伯和仲)酰胺的α-官能化同时包含未活化的α-C-H键和具有竞争活性的N-H键,仍然难以捉摸。本文显示的是脂肪族酰胺(包括仲NH酰胺)的一般有效氧化α-氧化胺化和羟基化反应。这种具有高化学选择性的无过渡金属化学物质为α-羟基酰胺提供了一种有效的方法。该氧化方案可显着实现惰性α-C-H键的选择性功能化,并完全保留活性N-H键。

  • Zirconium catalyzed amide formation without water scavenging
    作者:Helena Lundberg、Fredrik Tinnis、Hans Adolfsson
    DOI:10.1002/aoc.5062
    日期:2019.9
    A scalable homogeneous metal‐catalyzed protocol for direct amidation of carboxylic acids is presented. The use of 2–10 mol% of the commercially available Zr(Cp)2(OTf)2·THF results in high yields of amides at moderate temperature, using an operationally convenient reaction protocol that circumvents the use of water scavenging techniques.

    characterized. Complex 1 bearing the 1,3-dibenzylbenzimidazolin-2-ylidene ligand is able to selectively catalyze both dehydrogenative amidation, mono-, and diamination (N-alkylation) through coupling of simple alcohols with amines effectively yielding a range of amides and secondary and tertiary amines. Selectivity is achieved by controlling the fate of the common hemiaminal intermediate, which in turn can be
