A para-selective CH amidation of simplearenes with nitriles has been developed. By increasing the amount of arenes, a further meta-selective CH arylation of the produced amides occurred. Both steric and electronic effects are utilized to control the selectivity, resulting in only para-selectiveamidation products. The readily available nitriles as amidation reagents instead of amides makes the synthesis

Synthesis of α-ketoamides using potassium superoxide (KO2) as an oxidizing agent
A simple and convenient method for the synthesis of α-ketoamides by the oxidation of aryl acetamides using potassium superoxide (KO2) as an oxidizingagent is disclosed here. The scope of the developed method is successfully tested with fifteen substrates. In addition, the utility of method has been demonstrated by synthesizing an orexin receptor antagonist, a medicinally interesting compound.

the ligand scaffold is synthesized and its catalytic efficacy for the direct synthesis of the amide fromalkyne and sodium azide in acidic water is evaluated. Catalyst 1 readily converts a wide range of internal and terminalalkynes to the corresponding amides with low catalyst loading in TFA/DCE (2 mL, 1:1 v/v) at room temperature in short reaction time (2h) and without the use of Ag(I) additive.

合成了在配体骨架上带有吡啶基的Au(I)-NHC络合物[L 1 AuBr](1),并评估了其在酸性水中由炔烃和叠氮化钠直接合成酰胺的催化效果。催化剂1在TFA / DCE(2 mL,1:1 v / v)中催化剂负载量低的情况下,很容易将各种内部和末端炔烃转化为相应的酰胺)在室温下以较短的反应时间(2 h)进行,并且不使用Ag(I)添加剂。不含吡啶基片段的相关催化剂显示出明显较低的活性,说明了启动子配体对水活化的作用。机理研究表明,炔烃最初会水合成酮,然后进行Schmidt反应生成酰胺。
