synthesis of amides has been explored by using secondary alcohols, Cu(ClO4)2·6H2O as a catalyst, and trimethylsilyl azide (TMSN3) as a nitrogen source in the presence of 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ) at ambient temperature. This method has been successfully adapted to the preparation of azides directly from their corresponding alcohols and offers excellent chemoselectivity in the formation
The first direct one-pot approach for the synthesis of N-substituted amidoximes from secondary amides or the intermediate amides has been developed. Through the Ph3P–I2-mediated dehydrative condensation, a variety of N-aryl and N-alkyl amidoximes (R1(CNOH)NHR2, where R1 or R2 = aryl, alkyl, or benzyl) were readily afforded under mild conditions and short reaction times. The synthetic application of

tetrafluoroborates have been coupled with arylboron compounds, carbon monoxide, and ammonia to give aryl amides in high yields. A saturated N-heterocyclic carbene (NHC) ligand, H 2 IPr was used with palladium(II) acetate to give the active catalyst. A mechanism is proposed for this novel four-component couplingreaction.
芳基重氮四氟硼酸盐已与芳基硼化合物、一氧化碳和氨偶联,以高收率得到芳基酰胺。将饱和的 N-杂环卡宾 (NHC) 配体 H 2 IPr 与乙酸钯 (II) 一起使用以得到活性催化剂。为这种新颖的四组分偶联反应提出了一种机制。
