金催化的β-区域选择性正式[3 + 2]酰胺与吡咯并[1,2- b ]吲唑的环加成反应:反应发展和机理研究
摘要:
在这里,我们报道了前所未有的金(I)诱导的酰胺与吡啶并[1,2- b ]吲唑的金(I)诱导的β位区域选择性形式[3 + 2]环加成反应,得到3-酰胺基7-(吡啶-2'-基吲哚具有良好的优良收率。首次分离了金(I)催化剂与乙酰胺的配合物,并首次通过X射线衍射分析对其进行了表征。机理研究表明,该反应途径涉及金稳定的碳正离子中间体,该中间体依次参与了苯环邻位的连续C–H键功能化。

Hydrogen-Borrowing Reduction/Dehydrogenative Aromatization of Nitroarenes through Visible-Light-Induced Energy Transfer: An Entry to Pyrimidoindazoles and Carbazoles
reduction/dehydrogenation aromatization/cyclization of nitroarenes by energy transfer. The present protocol does not require additional oxidants, hydrogen acceptors, and hydrogen evolution metal catalysts. The mechanistic studies demonstrated that the hydrogen-borrowing reduction/dehydrogenative aromatization process was initiated by the formation of active singlet species through efficient energy transfer
