acidity and miscibility, have been developed to promote the Ritterreaction. Among them, [BSmim]CuPW12O40 [BSmim = 1-methyl-3-(4-sulfobutyl)-1H-imidazol-3-ium] displayed the highest activity for the amidation of a variety of alcohols with nitriles, delivering the corresponding amide products in good to excellent yields. Furthermore, the reaction can be easily scaled up to a gram scale without losing efficiency
已经开发了一系列多金属氧酸盐-离子液体催化剂,结合了多金属氧酸盐和离子液体的特性,并引入了酸性和混溶性,以促进 Ritter 反应。其中,[BSmim]CuPW 12 O 40 [BSmim = 1-methyl-3-(4-sulfobutyl)-1 H -imidazol -3-ium]对多种醇与腈的酰胺化活性最高,相应的酰胺产品的收率很好。此外,反应可以很容易地放大到克级,而不会损失效率。因此,该方法提供了一种使用多金属氧酸盐-离子液体基催化剂通过 Ritter 反应制备酰胺的有吸引力的方法。

Enantioselective Reductive Cyanation and Phosphonylation of Secondary Amides by Iridium and Chiral Thiourea Sequential Catalysis
and phosphonylation of secondary amides have been accomplished for the first time for the synthesis of enantioenriched chiral α‐aminonitriles and α‐aminophosphonates. The protocol is highly efficient and enantioselective, providing a novel route to the synthesis of optically active α‐functionalized amines from the simple, readily available feedstocks. In addition, the reactions are scalable and the
