已成功开发出一种有效的多相钯-多金属氧酸盐钯-H 6 PV 3 Mo 9 O 40 / C催化剂,用于通过碳-氢(CH)活化和碳-氮(CN)形成碳-碳(CC)键通过使用氧作为末端氧化剂的氧化胺化形成键。偶联过程很简单,并且使用相对温和的条件来形成所需的产物。此外,由于不需要其他试剂(例如有机/无机氧化剂),因此产生的废物更少,并且水是唯一产生的副产物。
The C-H activation of aryl amide using readily available Pd(OAc)(2) in the presence of selectfluor is reported. The highly mono-selective introduction of sp(2) hybridized functional groups have been realized. A broad range of aryl-, alkenyl- and keto-aryl amides were prepared using unactivated coupling partners under mild conditions. (C) 2018 Elsevier Ltd. All rights reserved.
